GMT Time check: ASTER - 20:29:27, GMT 20:26:00 
 
Thus, aster is 3 min, 27 sec ahead of coordinated universal time. 
 
The monocle compass/rangefinder was set to 1:28 pm, local two minutes later, 
so it should be correct. 
 
 

ragwort crashed while adding barometer 
 
I think I killed the barometer board while connecting it to the system, which then 
sent bad data which crashes ragwort.  The barometer is back out of the system. 
 
 

taoil.3cm and tsoil.10cm swapped in preprocess.config 
to match the probe placement. Covar output prior 
to this time will have these channels swapped. 
 
covar and xcockpit for marigold were restarted. 
 

PROP WIND DIRECTIONS: 
 
	Prop. wind directions were shot with the Nikon 
today. They are listed below. A second person should 
do a check to verify these numbers. 
These angles have been entered in the sensors at about 
23:30 GMT on JD46. 
 
prop	angle 
 
1m	145.0 
2m	145.8 
4m	145.8 
7m	145.8 
10m	145.3 
 
 

BAROMETER: 
 
	The channel_config file was changed for 
ragwort serial channel 202, ie, barometer. The 
communication parameters were changed to 1200,7,7. 
Ragwort data collection was turned off then on at 
about 00:10 GMT. 
 

Sunset now! 
 
 

Pre-arm sonic zeros: (done 2/13/91) 
 
Note that these were done after thresholds changed somewhat, but  
without changing the triggering point. 
 
SUW1:  A: -138 +/-3   B:  +11 +/-4  C:  +28 +/- 3 
 
SUW2:  A: +196 +/- 4  B: -164 +/-9  C: +170 +/- 9 
(Note: transducers switched: path B top&bottom) 
(Note: noise level is higher than SUW1 - possibly because of 
the extension to the transducer cables) 
 
SAT3:  U: +21 +/-.5   V: -86 +/-2   W: +79 +/-1 
(Note: the HC11 coefficients haven't been changed yet)

level history to date: 
 
levels were first hooked up Wed (I think) to 4m uw.  Since the "pigtail" 
cable was labeled backwards, these channels were hooked up to the 10m 
channels (ragwort 106&107) and pitch and roll were probably reversed. 
 
On Thurs, I did several tests (including loosening the back guys to 
check the change in angle and ended up with levels hooked up to the 
10m uw on the right channels.  The result of these tests were that 
I think the BNCs on the display unit are labeled correctly (since 
"P" changed by .4 deg (from .42 tight to .00 loose) and "R" changed  
by .1 deg (from 1.2 tight to 1.1 loose) with the back guy loosened. 
This means that "Y" on the display is roll and "X" is pitch.  This 
should all be confirmed at the end of the experiment. 
 
On Fri (again, I'm not sure of the day) I switched back to the 4m uw 
now on the right channels. 
 
Today (Sat) I noticed that xcockpit showed that pitch.4m had changed 
from about -1.8 to -1.0 overnight - I'll check the guy wires today. 
 
Also, the cables are labeled strangly in the level box.  At the  
moment they are: 
Red "18m" goes to the 10m uw 
Red unlabeled goes to the 4m uw 
BNC "A" is ragwort:107 (roll.10m) 
BNC "B" is ragwort:106 (pitch.10m) 
BNC "C" is ragwort:105 (roll.4m) 
BNC "D" is ragwort:104 (pitch.4m) 
I should get to relabeling these cables today, since this is too 
much for a normal human (myself included) to understand. 
 
 

Cables switched on ATI 
 
I had hooked up the sonic transducer cables wrong, which was causing v and w 
to be negative (and probably also responsible for the large biases I had seen). 
I switched VR1&VR2 and WR1&WR2.  This should improve matters greatly! 
 
Note that zeros on this sonic must now be checked again. 
 
 

Soil sample taken about 1930 (1230, local) 
 
Saturday's container is now full. 
 
 

Levels switched from 4m to 10m. 
 
I just labeled all of the cables also, so anyone should be able to  
do this task now. 
 
 

Time reset on ASTER 
 
Before doing this, I shut down everything (even ingest).  Then I used the 
date command (as su) and restarted everything.  I think everything is going 
now - check_aster, raw_data, and xcockpits look okay. 
 
Note that I couldn't reach NIST, so I used the time difference I remembered 
from yesterday.  I also reset cocklebur's time at the same time (from the 
ASTER xclock display), which caused cocklebur to be about 1.5 seconds slow. 
 
I think overall that we are within 5 seconds of UTC, so I'm happy. 
 
 

ARM IOP #1 
 
	All systems go for ASTER. There is some 
spiking on the 4m UW sonic, mostly in the u component. 
The fast q at 10m is off scale according to cockpit. 
The psp.in is also off scale on cockpit. Will do some 
further investigating. 
 
 

PSP.IN status: 
 
	The psp.in sensor is working ok. 
Output is -.26 W/m^2. 
 

FAST Q status: 
 
	Output of sensor agrees with previous 
plots at this time of day, ~12 gm/m^3. 
 

RESTART COVAR_RAGWORT: 
 
	Covar_ragwort was restarted to add the 
pressure data to the mean calculations. The script 
covar_ragwort had defined the did's for pressure but 
they were not in the call to covar. 
This was done at 16:58 GMT. 
 

POWER CRASH! 
 
	A power glitch happened at 20:50 GMT. 
The UPS did not kick in so ASTER went down. 
The power glitch caused the bridge to lock up. 
After recycling power to the bridge, went out to 
array to reset each ADAM. 
System was up and running at 21:40 GMT. 
 
Will do some tests on the UPS to see why it failed. 
 

SOIL SAMPLE: 
 
	A soil sample was collected at about 20:30 GMT. 
 

LEVEL SENSORS: 
 
	Level sensors were changed from 10m to 
4m at about 20:30 GMT. 
 

UPS TEST: 
 
	The test mode on the UPS worked ok. 
This automatically shuts off AC to the UPS input 
and runs the inverter for ~20 secs. 
Why it did not work before is a mystery. 
 

covar output is now split into one file for each julian date.  
This is done via crontab at 5 minutes past midnight 
everyday. 
 
The output goes in a file with the Julian date appended, eg: 
 
comos.covar.048  ragwort.covar.048  marigold.covar.048 
 
These files may be found in the usual place,ie. 
$ASTER/projects/ARM91/results/covar/ 
 
Two scits are used for this : scripts/covar_daily and 
scripts/covar_split. covar_daily is called by crontab. 
This script in turn calls covar_split. 
 
 

All sonics look clean during this shift so far (since 0045 MST) 
 
Also note that I have changed the scale in preprocess.config to let c go down 
to 320 m/s, since it is about 329 tonight. 
 
 

Dawn is breaking now. 
 
 

Light frost is on the ground. 
 
 

Sunrise!!! 
 
 
 

Prop directions off by 180 degrees. 
 
Steve S. confirmed this this morning (boom orientations entered as the angle sighted - 
which is the direction the wind sensor is facing, rather than the direction it is 
pointing).  We'll wait until after this IOP the change it back. 
 
 
 

ATI sonic has started spiking moderately 
 
UW.4m also has a few, now that the winds have picked up to about 8 m/s. 
UW.10m looks perfect (knock on wood!). 
 
 
 

Reservoir bottles are mostly frozen still 
 
Steve and I just opened up the 1 and 2m units to check - only about 
3 mm of water is not frozen around the side of the main reservoir bottle. 
We'll just wait for them to thaw. 
 
 

SOIL SAMPLE: 
 
	A soil sample was taken at 19:20 GMT. 
 

LEVEL CHANGE: 
 
	Sonic level inputs were changed at 
19:25 GMT. Changed from 4m to 10m. 
 

SONIC SPIKES: 
 
	There has been some spiking on the 4m uw sonic 
thru out the day. The 4m ati also has spikes, mostly on 
the u component. 
 

IOP #1 DONE: 
 
	The first IOP has ended at 01:00 GMT on 
julian day 50. 
 

NEW WIND DIRECTIONS: 
 
	The wind direction error has been corrected. 
180 was added to each sensors' direction parameter. 
Below is the direction values entered. 
 
sensor (channel #)		direction 
 
1m (200)			325.0 
2m (201)			325.8 
4m (202)			325.8 
7m (203)			325.8 
10m (204)			325.3 
 
 

DAILY PLOTS for JD 49: 
 
	The daily plots, for data from 
ragwort and marigold, have been cut-off at 
about 22:00 GMT. This maybe due to a bug in 
the script to split the covar data files into 
day files. I was running graph routines after 
20:00 GMT for day JD 49 while still in JD 49. 
Maybe executing plots during the last cycle of 
syncserver for the day has some effect. 
Need to talk to Charlie about it. 
 

GRAPH_COV: 
 
	The version of graph_cov was destroyed. 
The plots for day JD 49 used graph_cov~. Need to  
confirm with Steve or Charlie about the latest version. 
 

4m KYPTON CALIBRATIONS: 
 
	The calibrations for the 4m Krypton 
were added to the preprocess.config file. 
We will need to make some changes to the calibration 
software since the path length is different from the 
10m unit. 
 

COVAR FILES for RAGWORT & MARIGOLD: 
 
	Ran covar_split manually on marigold and 
ragwort for day 49. Plots now have 24 hours. 
 

SOIL SAMPLES: 
 
	Soil sample taken at 21:00 GMT. 
 

GILL SONIC: 
 
	The Gill sonic was hooked up today. 
Only minor problems had to be dealt with. 
Proper calibrations have been entered into preprocess.config. 
Looking at cockpit, output signals agree with the ati sonic. 
 

COVAR TASKS: 
 
	Killed and restarted covar tasks to take 
into account the new pathlength parameter for the 4m 
h2o sensor. The sensor has not been hooked up yet.

SONIC LEVELS: 
 
	Sonic levels were changed when soil samples were 
taken, around 22:00 GMT. 
Change from 10m to 4m. 
 

H2O at 4m: 
 
	The 4m Krypton was added to the 
network around 23:45 GMT. Signal output looks 
low. Will need to monitor. 
 

disk full - archiving stopped manually. 
 
I will restart archiving after backup is done (and reset xgsetroot!) 
 

archiving again 
 
 

ATI COMPARISON SONIC: 
 
	The ATI comparison sonic was added to the system 
today. Instead of speed of sound the last parameter is 
temperature. Eventhing looks good. 
 

LEVEL CHANGE: 
 
	Levels were changed from 4m to 10m at 19:20 GMT. 
 

SOIL SAMPLE: 
 
	Soil sample taken at 19:15 GMT. 
 

Covar's started - ragwort was off 
 
I've just restarted all covar processes after the UPS test reboot this morning. 
I've noticed that covar on ragwort was never restarted last night (probably after 
the Krypton was added), so last night and this morning will be missing. 
 
 

2m prop boom releveled by eye 
 
I noticed that this boom seemed to be sagging, so I reseated the yoke.  This probably 
changed the height by about 2 cm.

FAST T: 
 
	The uw tower was lowered to work on the 4m 
sonic. While this was being done, the fast T sensor gains 
were checked. Below is the results of that test. 
 
sensor		gain 
 
uw.4m		5.1 +- .01 
 
uw.10m		5.08 +- .02 
 
ati.4m		5.1 +- .01 
 
 

FAST Q: 
 
	The 10m krypton windows were cleaned while 
the uw tower was down. There was no major change in its 
output. 
 

UW TOWER: 
 
	The uw tower is back in a vertical position (23:50 GMT). 
 

SYSTEM STATUS: 
 
	System looks good. All Adams responding and 
sending data. 
 

SONIC SPIKES: 
 
	There were a few spikes on the uw sonics last 
night. 
The intercomparison sonics look good. 
 

heat flux for JD 51 has problem with data files and will not create 
a graph for the logbook.  
 

SOIL SAMPLE: 
 
	Thursday soil sample was taken at 20:50 GMT. 
 

LEVEL CHANGE: 
 
	Sonic level changed, at 20:55 GMT, from 
10m to 4m. 
 

PROP WIND DIRECTIONNS: 
 
	Prop. wind directions were shot again with the Nickon today 
They are listed below along wwith the directions of all the sonics. 
These angle corrections will be entered into the prop sensors for 
JD 53. The towers were also sighted in for vertical alignment and bowing.

Project default name 
 
	the project default namme was changed from FLAT90 to ARM91. 
 
 

bkfiles_kill done on jd052 
 
I hope that this was okay - I did it from home 
(thanks Charlie for leaving tape_store.dir in /tmp!) 
Remember that the tape in the drive has data - I think I'll 
"offline" it just to be safe. 
 
Good night, aster. 
 
 
 

crontab edited to correct ups_stat path 
 
The crontab entry was trying to find ups_stat in /home/aster/bin4, 
but the subdirectory is really /sun4.  Hopefully, ups_stat will now 
work - we'll see tomorrow! 
 
 

SOIL SAMPLE: 
 
	Soil sample taken at 20:15 GMT. 
 

LEVEL CHANGE: 
 
	Levels changed from 4m to 10m at 20:20 GMT. 
 

a test 
 

Backup done and files killed - bad tape? 
 
This was done from home again.  This time I did not "mt offline", 
since we may want to append to this tape if no one gets out there 
tomorrow.  Note that this tape had some problems.  I got an I/O error 
the first time I ran bkfiles.  Then I rewound and did tape_init, which 
aborted with another I/O error and a core dump.  I rewound and tried 
tape_init again, which appeared to work normally.  Finally, I manually 
did "tape_store dummy rad prop psyc uw comp" (I hope I got the order 
right!), which also appeared to work - with the directory looking normal. 
 
I would have thrown out this tape and used another blank tape if I had 
been there, but I wasn't about to drive 2 hours just to recover today's 
data during a non-IOP.  Hopefully, whatever the problem was cleared itself. 
 
 

Author should default to last author in the session. 
 
Type already defaults this way, which is not as desirable since 
we mostly enter all comments of one type into one comment per 
session.  For example, this comment really has two pieces of 
information - one suggesting a default for author and another 
suggesting a lack of a default for type - which are being entered 
as one.  In this session, I might next comment on the weather or 
the performance of a sensor (though I won't since I am logged in 
remotely!), which would require totally different types. 
 
 

Power cycled on Exabyte drive 
 
Hopefully, this will also help recover from the problems I had last night. 
It is almost (but not quite) time for a tape cleaning. 
 
 

xcockpit died on ragwort overnight 
 
It had a segmentation fault, but all other processes look okay. 
 
 

Soil sample taken 
 
Looks a lot drier than when I did it before.  The first one I did I remember 
looking almost completely moist, the second was only dry in the first .7cm  
(or so), and this one looked moist only in the last .5cm. 
 
 

Levels switched from 10m to 4m 
 
 

We can't figure out how to change default project 
 
I edited comments.cmt (or something like that) last night, and it worked 
for last night's comments, but now it is back to the previous project. 
 
 

Sonics status from xcockpit: 
 
I cleared these plots yesterday (about 16 hours ago) 
UW4 - 3 spikes 
UW10 - 1 spike 
ATI.NCAR - 16+ spikes 
ATI.ATI - clean, but no V! (but it was good sometime - it has gone bad during the last 12 hours) 
GILL - clean 
 

Preprocess now has -15:20 for all temps (including fast Ts)  
 
It has been getting cold here - now -11! 
 
 

It was a clear night  
 
Lots of stars and I saw 2 meteors driving up here. 
 
 
 
 

Dawn is breaking 
 
 

Printer for sodar started as per Joel's phone call. 
 
You simply toggle the print mode in the VT320 setup menu (access by F3) 
Instructions are at the bottom of page 2 in Joel's instructions. 
 
This occured about 1 1/2 hours ago at 5:06 (local) 
 
 

Exabyte cleaned 
 
This was done in attempt to get tar to work.  I actually did it twice since the  
first time seemed too fast.  This finished up one cleaning cartridge which had 
other cleaning dates of: 
1/17/91 
1/25/91 
2/24/91 (now) 
 
 

cloud cover about 7/8 now! 
 
 

Sunrise (through an orange haze from clouds) 
 
 

UW.4m has biases 
 
I think I must never have switched the receive cards for AT and AB back when I was 
working on it on Wed.  I just went out to the masts and switched them back - this means 
that the biases will be different for the first 2 hours of this IOP.  (Better than 
nothing?) 
 
 

now 8/8 cloud cover - overcast 
 
(except for thin bands at the N,E,&S horizons) 
 
 

Snow flurries starting 
 
Joel called from Boulder to say that it was already snowing there. 
 
 

All sonics are having problems now 
 
The Gill looks the best, followed by the UW.4m 
Lots of spikes on UW.10m, a few on our ATI, and the ati ati 
would look okay except that its sonic-temperature is  terrible 
(also V is still out on the ati ati).  Winds are now gusting 
to 15 m/s, and T is about -1C.  Snow flurries in the air. 
 
 

several features for xstrip: 
 
- print JD in header line (with quit&chart buttons) so printed-out plots 
  are labeled. 
 
- have "pause" function to study plot for a while - I guess this could 
  be done now by slowing the chart speed way down, but this is clumsy. 
 
- print scales (somewhere?) 
 
 
 

linear_2 
 
There should be a version of linear built in which knows the A/D conversion factor 
and only needs the gain and bias in Volts (though it might be nice to put in the 
amplifier/filter board multiplier and offset settings also). 
 
 
 

T.4m.uw is now broken 
 
We'll (Tom and I) wander out to the masts and fix it if it looks safe. 
(We have to go out anyway to do the noon-time chores.) 
 
 

levels switched from 4m to 10m 
 
 

Soil sample taken  
 
There was some snow caught in the weeds, which I scraped off before taking the sample. 
One of the samples was fairly dry in the top layer, but the other two were quite moist. 
 
 

Fast T changed 
 
I climbed the tower (with Tom looking on).  The old one was definately  
broken. 
 
 

t.10m.uw just broke 
 
We aren't going to climb for this one - its down for the rest of this IOP. 
 
 

Ran bk_files, but got the following error message when 
extracting the table of contents: 
 
advancing to next file 
advancing to next file 
advancing to next file 
tar: tape read error: I/O error 
error reading tar file, status = 3 
Archive to tape completed 
 
Assuming that the data were actually on the tape per Martin 
and Oncley, I removed the backed-up data. 
 
 

Modified shocov so that it will accept multiple 
a:v:r specifications. The values are output  
in tabular form, with the columns in the same  
order as the command line switches. If a parameter 
is not found for a particular time step, "NA" 
(not availible) is put out. 
 
These tables will be useful for Splus, 
and (via xgsetup) can be fed into 
xgraph. 
 
I modified graph_rad to work with the new 
shocov - old method took 6:16, new method  
takes 1:10. 
 
All existing scripts should work (slowly) 
unmodified, since the shocov output for a single 
parameter is the same as before. 
 

everything nominal as they say; the previously mentioned 
dead sensors (v.ati.comp, t.10m.uw) have not come 
back to life. 
 
About a dozen spikes on *.10m.uw over the last three  
hours. Other sonics look clean 
 

sodar backed up 
 

COCKPIT-ragwort DOWN: 
 
	Cockpit for ragwort was not running. 
message on window refers to a major opcode of request failed: 
7 (X_ReparentWindow). 
 
restarted cockpit. 
 

ATI - v component: 
 
	v component on the ATI sonic looks ok, using 
xstrip. Winds right now are quite light. 
 

FAST T TRANSDUCER CHANGED 
 
The UW tower was lowered and RAGWORT:101 fast T transducer was  
changed and calibrated. The fast T transducer "ragwort:100" 
was also calibrated. The values are as follows: 
 
transducer 100        absolute temp = +.05 
			       gain = 5.02 + - .02 
 
transducer 101	      absolute temp = +.06 
			       gain = 5.025 + - .015 
 
The gain readings were taken from a preprocess file, and  
averaged over several readiings. 
 
 
 
 

UW tower back up: 
 
	The uw tower is backup. Fast T units 
look good. 
 

SONIC SPIKING: 
 
	There is excessive spiking on the 4m and 10m 
uw sonics, on both the u and v components. There is 
also spiking on the ncar ati unit. The Gill and the ATI 
sonic look good.

The Wed - Sun samples were in plastic, the Mon was taken just before weighing 
fresh. We collected 4 Monday samples, tony did the Official one 
and Kirt, Steve S and Lou did the other three. A triplicate of the official 
Monday was weighed fresh, the remainder of the official Monday was stored in 
plastic, the other three samples were also stored. 
 
NOTE: While removing samples from oven, the upper rack slipped and spilled some of 
the samples, namely days Sat, Sun, Mon. Therefore you should use this data 
with caution. 
 A second Monday weigthing will be done with Tuesday weigthing. 
 

LEVEL CHANGE: 
 
	Change from 10m to 4m at 22:50 GMT. 
 

SODAR PRINTER OFF: 
 
	Sodar printer was disabled today at about 
22:35 GMT. 
 

DISK FULL!!! 
 
	The archive data was not transferred to disk 
last night; therefore, the disk filled up. Archiving 
stopped at about 06:00 GMT. Charlie tryed to run bkfiles from 
Boulder this morning but had no luck. 
 

SENSOR STATUS: 
 
	Sensors look good. There was spiking throughout 
the night on the 4m and 10m uw sonics. Spikes occurred on 
both the u and v components. 
	The v component on the ATI unit was off scale at times 
during the night, while the other two comparison units were not. 
 

EXABYTE TROUBLES: 
 
	The exabyte drive has gone south for the 
winter. We can not get it to initialize a tape. The 
only message back is "status = 138". The power has been 
recycled, the head has been cleaned, and 3 different tapes 
have been tryed. People are looking into the options of 
borrowing a drive from STOUT or renting one. 
 
Because the data set we wish to archive is during an iop, 
the archive processes have been shut down so that we do not 
run out of disk space. 
 

COVAR for COSMOS: 
 
	Covar_cosmos was restarted to include the 
gill and ati sonics. This took place at 19:55 GMT. 
 

EXABYTE round TWO! 
 
	After playing around with the exabyte; cycling power, 
trying tar commands, etc., I was able to get it to tar the backup 
files to a tape. A tar read showed all files were on tape. 
I then proceeded to try bkfiles again. Of course, everthing worked 
ok! We will still replace our drive with the loaner from stout. 
 

ARCHIVE GOING: 
 
	Restarted archiving of data after getting bkfiles 
to run, time was 20:38 (GMT). 
 

LEVEL CHANGE: 
 
	Level input changed from 4m to 10m at 21:05 GMT. 
 

SOIL SAMPLE: 
 
	Soil sample taken at 21:00 GMT. 
 

LICOR SENSORS: 
 
	The licor sensors have been added to the 
system at about 23:30 GMT. These sensors have been 
added to routine covar_marigold which will be restarted 
at 00:00 GMT day 58. Preprocess has also been modified 
with the correct coefficients. Below is a table providing 
pertinent information. 
 
ADAM CHANNEL	SENSOR          ID		CALIBRATION 
 
113		licor.out     py10835		.078992779 
114		licor.out     py13331		.059530038 
 

COSMOS A/D STOPPED: 
 
	It was noticed in cockpit that the analog channels 
from cosmos were not running. A "data_off" /"data_on" was 
required to get it going again. This occurred at about 
00:55 GMT. 
 
Note that the gill file starts late because of this and that 
the ncar file is short because the fast T wasn't recorded initially. 
(spo) 
 
 

wets are frozen, as usual 
 
Pretty good agreement between the wet and dry temps, though. 
 
 

Wrong baro filename 
 
A bad timetag caused one of the baro files last night to have 
the wrong name - I've just renamed it back to baro058080008, since 
data_dump said that that was the first good timetag. 
 
 

STATUS: 
 
	Everything is up and running. No spiking on 
the sonics. The licor.in sensor looks like it might be 
wired backward. Will look at some plots to decide. 
 

SOIL SAMPLE: 
 
	A soil sample was taken at about 20:30 GMT. 
For a more precise time, look at a plot of the level 
sense signals to see when they were changed. 
 

LEVEL CHANGE: 
 
	The level signals were changed from 10m to 4m at 
20:35 GMT. 
 

3cm soil samples for JD 56 and 57: 
 
	Below are the results for Monday, 26 and Tuesday, 27, 
soil samples. A second Monday sample was done because of the 
loss of dry soil the day before (refer to log enter 107 for more info). 
 
			Monday (56)		Tuesday (57) 
			   26			  27 
 
A	fresh		30.79			32.66 
	dry		29.26			31.31 
	delta		 1.53			 1.35 
	%		 5.23			 4.31 
 
B	fresh		35.30			29.76 
	dry		33.51			28.55 
	delta		 1.79			 1.21 
	%		 5.34			 4.24 
 
C	fresh		30.96			29.36 
	dry		29.43			28.19 
	delta		 1.53			 1.17 
	%		 5.20			 4.15 
 
 
	mean %		 5.26			 4.23 
 
 
	 
 

EXTABYE TEST: 
 
	Tyed running "tape_store" on exabyte. 
It did not work; bombed in initializing. So I 
tryed a separate "tape_init", this worked. 
Tryed "tape_store" again, everything worked up until 
it tryed to read the directory. 
Will try again tonight. 
 

PREPROCESS.CONFIG CHANGE: 
 
	Changed limits for licor sensors, in preprocess.config, 
to conform with psp sensors. 
 

IOP # 3: 
 
	IOP #3 starts at 03:00 GMT. 
ASTER is up and running. All sensors are responding 
and looking good. The sodar printer was restarted for 
the IOP. 
 

TAPE ARCHIVE for JD 58: 
 
	Archiving of data for JD 58 went ok. 
The exabyte ran smoothly. I'll leave power on and 
try using the drive later tonight. 
 

CMP_EPLI - a new graph: 
 
	"cmp_epli" is a plot to display the 
difference between the epply psp sensors and the 
licor. The user has the option to diplay the licor 
data on the y axis and the psp on the x or they may 
wish to display the difference (psp-licor) on the 
y axis and psp on the x. One must also choose if they 
wish to look at in coming or out going radiation. 
 
USAGE: cmp_epli  <-o -i> <-d> 
 
if <-d> is left out, then a plot of psp vs licor 
will be presented. 
 

EXABYTE TESTS: 
 
	Ran the exabyte with "tape_store" 6 times. 
The first test was with a "used" tape. Tape error messages 
resulted. With a new tape, each run was sucessful (6 runs 
on on tape). 
	The drive rack was pulled out; however, I do not think 
that had anything to do with it. 
 

INGEST STOPPED on ALL ADAMS: 
 
	At 7:52 GMT, the ingestors stopped on all adams. 
Upon examination of syslog, error messages from ingest: 
ingest> Error reading stream message, rval:0, errno:54 
 
Archiving was running again at 08:00 GMT. 
covars were back up at 08:05 GMT. 
 
Possible cause: I was working on the exabyte drive at 
the time of the crash. Maybe I bumped a switch on the optical 
bridge. 
 

BRIGHT NIGHT! 
 
	Took a short walk in the moonlight. 
With a night like this you don't need any 
flashlight! 
 

SONIC SIGNALS: 
 
	Since restarting cockpit, 08:00 GMT, the sonics 
are looking good except for the w component on the ati comparison. 
There was more deviation on its signal compared to the others. 
 

EXABYTE TESTS: 
 
	After putting the exabyte all back together, 08:00 GMT, 
I have run tape_init and tape_store a minimum of 5 times dumping 
the directories prop, psyc, uw, comp, rad. There has not been 
a failure. 
	While putting the unit back together, I re-routed the 
cable from the Exabyte to the computer such that it is not 
as close to the power transformer and fan as it use to be. 
Maybe this is where our problem was. 
	We'll continue to run more tests throughout the morning. 
 

v.ati.ati has just gone bad 
 
The temperature has just dropped from 0 to -2 C.  Just in the last 2 xcockpit scans,  
v has developed -5 and -10 m/s spikes - looks like its headed offscale. 
Temperature looks a bit spikey also, but not terrible (on the large scale). 
As of the 3rd scan, v is offscale except for a few spikes. 
 
All other sonics look good. 
 
 

w.ati.ati and t now bad also 
 
They are very noisy w.r.t. the other sonics.  w varies 1 m/s peak-to-peak, while 
our ati is 0.4 m/s and t varies 7 C pp vs. 1 C. 
 
U still looks okay! 
 
 

Dawn is breaking 
 
(The full moon setting along the line of the power lines 
looks pretty nice also.) 
 
  
 

Sunrise! 
 
 

Quick fix: chmod -w params.cmt 
 
This doesn't allow logbook to change our default project ID. 
Logbook complains at the beginning, though. 
 
 

ati.ati sonic back alive on all channels 
 
T = -1 C now - I've made a bunch of plots documenting the failure.  It definately 
tracks with temperature, v going out at -4C. 
 
All other sonics haven't spiked at all this shift. 
 
 

pitch.4m had a level shift 
 
I've seen this before.  It happened sometime this shift - probably from 1200-1400 GMT. 
The pitch output increased by about .5 degree and is now steady at a new value.  Since 
there is no appreciable wind (1m/s) it is hard to imagine that this is real.  The 
shift seems to have been instantaneous (no ramp visible on xcockpit). 
 
This will require further investigation. 
 
 

Strange vertical velocities this morning 
 
There have been some wild w changes - up to +/- 1 m/s changes in a few seconds. 
I guess these are isolated plumes getting started just after sunrise. 
 
 

Now high overcast  
 
was 1/8 cirrus overnight. 
 
 

Prop at 4m stalled 
 
THe winds were light, but the other 4 props were still going.  Perhaps 
its time to service the bearings on this one (ID003). 
 
 

graph_cov and graph_mean sped up 
 
These now have the multivariable shocov calls and are tolerably fast. 
 
 

Winds often calm 
 
During the last hour, the winds have often been calm (props stalled).  This 
period can be used for sonic zero checks.  Also, believe it or not, the 
temperature profile is unstable (despite the overcast sky) so this should 
be free convection data.  I would interpret fluxes, though, with a grain 
of salt. 
 
 

Switched sonic levels from 4m to 10m 
at 19:35. 
 
 

SPO took soil samples at 19:30, 
and weighed today's wet samples 
and yesterday's dry samples. 
 
 

Quick fix for metalog screwed up the -v 
(vi) option.  I reenabled write permission 
on params.cmt.  However metalog is now 
retaining the ARM91 project id! 
 
 

10m Speed and Direction Plots 
 
I rewrote some scripts to implement the 10m 
speed and direction plots for ARM91.  The  
script ~aster/scripts/comp_uv10m writes a  
file with the prop vane u and v wind components 
from all levels and places it in the directory 
ARM91/results/profiles.  The output file is named 
prop#.  The script is executed as 
comp_uv10m .   
 
The plot is made from S using, e.g.  
fun.winds("profiles/prop#059").  The exact  
file name depends on the directory from which  
you are running S.  Any directory under  
~aster will work; the example assumes  
~aster/projects/ARM91/results.  The source 
file for the S function is ~horst/sfun/winds.platte. 
 
I plotted all past data, including that prior 
to Feb 19 when the wind direction error in the 
prop vanes was corrected.  For data prior to 
Feb 19, I added commands to winds.platte to 
multiply the u and v wind components by -1. 
This S function source file is ~horst/sfun/ 
winds.platte.err. 
 
 

1m wet bulb appears too warm. 
Need to keep an eye on it if it 
ever thaws again. 
 
 

Disabled sodar printer: 
Auto print mode -> normal print mode 
 
 

SOIL SAMPLE: 
 
Soil sample taken at 18:20 GMT. 
 

LEVEL CHANGE: 
 
	Level signals changed at 18:25 GMT from 
10m to 4m. 
 

ATI SONIC WORK: 
 
	Gary Zimmerman is working on the ATI sonic at 
this moment. He replaced both the v and w transducer pairs. 
 
follow up: Gary finished working on the sonic. He could not find 
any obvious reason for the failure. This was expected since it 
appeared to be a temperature problem. He adjusted the pots to 
accommodate the new transducers. Work was completed at around 
19:00 GMT. 
 

PARAMETER PROJECT LOOKS GOOD! 
 
	I played around with metalog to get it to 
default the project name correctly. It seems to be 
working now. What I did was delete all params.* files. 
Logbook then created a new file with the correct project 
name. Maybe this file has something to do with it. 
 
 

7m WET BULB is DRY: 
 
	The 7m wet bulb appears to have gone 
dry. Tomorrow we will change the wicks. 
 

SONIC CONDITIONS: 
 
	Some spiking has been going on on the 10m 
uw sonic. This has been on the v component. 
Since Gary worked on the ati sonic everything up to now 
has looked good. 
 

LOGBOOK PROJECT FIX FAILED: 
 
	The fix to logbook project default has 
failed. It almost seems like logbook does an update 
on its own and graps some past file with FLAT90 in it. 
 
 

Strong winds around 2400 on JD 60 caused 
spiking on NCAR ATI and 10m UW sonics. 
 
 

checked aster - everything looks okay 
 

IOP #4: 
 
	IOP #4 started at 13:00 GMT. This is a joint 
IOP with WISP. 
 
	System is up and running. All sensors are 
responding except for the pygreometers. They were removed 
yesterday morning for testing of the tdome/tcase measurements. 
If needed, they will be installed today. 
 

SONIC SPIKING: 
 
	There were a few spikes, throughout the night, 
on the 4m and 10m uw sonics, v component. 
 The ncar ati had a number of spikes on all 3 components. 
The ati sonic looks good, so does the gill. 
 
 

SODAR PRINTER: 
 
	The sodar printer was started up for the IOP. 
 

FALSE IOP! 
 
	Due to a miss communication over the operational 
status messaages, ARM did not go operational this morning. 
WISP was operational. 
 THAT IS ALL! 
 

SOIL SAMPLE: 
 
	Tony took a soil sample around 23:00 GMT. 
This included 10cm and 30cm samples. 
 

LEVEL CHANGE: 
 
	level signals changed from 4m to 10m, 
23:00 GMT. 
 

SONIC SPIKES: 
 
	There has been a lot of spiking on the ncar ati 
sonic today. Mostly on the w component and little on the u. 
The ati soinc looks ok with a few soikes on the w. 
 

PYRGEOMETER SENSORS: 
        The pygs were removed by Tony at 08:30 - 08:50 on Friday 1 March 
and taken to the lab for temperature calibration. 
	The pygs were added back into the system today, Saturday 2 March 
around 22:30 GMT. They are now sending data for tdome and 
tcase. Software is being worked on to make the data useful. 
 
	Below is the amplifier/filter settings and channel 
assignment. In addition are the calibration coefficients.

COVAR MARIGOLD: 
 
Covar for marigold was stopped and started to use 
new calibrations for pygreometer temperatures. 
 

SOIL SAMPLE; 
 
	Soil sample taken at 22:05 GMT. 
 

LEVEL CHANGE: 
 
	The level signals changed from 10m to 4m 
at 22:00 GMT. 
 
	The cabling, analog cable, from the level signals 
was changed to a short cable today. This was done inorder 
to have an analog cable for the Vaisala probe attached to 
the 4m Kypton. Refer to logbook enter on operations, for today, 
for more information. 
 

VAISALA HUMIDITY at 4m UW: 
 
	Since the Krypton instruments are not agreeing 
well with each other, the decision was made to add a third, 
independent humidity sensor. One of the Vaisala units was 
choosen (it had recently came back from the factory calibrated) 
The unit was mounted at the 4m height coming off the west side of 
the Krypton unit. 
Below is information on channel assignment, gain/filter, etc. 
The sensor was interfaced to ragwort. 
The sample rate was set to 20.

rh.vaisala.4m	108		10 /w offset 5		10 
 
did #: 710      calibration: linear(0.001525925,50.0) 
 

HUMIDITY INTERCOMPARISON: 
 
	The Vaisala and Rotronic instruments 
were added to the array today. They are interface 
to cosmos. In addition, the spare psychrometer was 
added as a reference to compare against. The height 
from the ground to the air intake is 1.4m. 
Below are the critical parameters are interfacing.

CONFIG CHANGES: 
 
	The necessary changes have been made to the configuration 
files to handle the new sensors. The changes to archive will 
start at 00:00 GMT for day 63. These changes are removal 
of sub-directory /psyc/varo, addition of vaisala.4m.uw to 
uw/uw04m, and creation of sub-directory comp/humidity. 
No changes were required yesterday for the addition of 
temperature information on the pygs (we were already collecting 
that data). 
 

POWER OUTAGE: 
 
	There was a power outage today around 
19:00 GMT. Everything was backup at 19:35 GMT. 
 

LOGBOOK FIX!!! 
 
	The default for projects works now. 
The problem was the new version for the script 
logbook was not moved to $ASTER/`arch'. 
 
NOTE: logbook does not want to work under 
cocklebur, Charlie should have the answer. 
 

ERROR in PYG TEMPS; 
 
	Looking at today's data, there is 
an error in the calculation of pyg. temperatures. 
From my testing it appears to be in the way the 
coefficients are pass to the calibration routine. 
With coeficients of 1, thigns calculate correctly. 
We shall find a solution tomorrow! 
 

7m TWET is DRY: 
 
	The 7m twet bulb has been dry all day. 
It will be taken caare of tomorrow. 
 

PSYC TOWER WORK: 
 
	The psyc. tower was lowered to work 
on the psychrometers. Their wicks were changed  
and bottles filled. This took place from about 
17:30 to 19:10 GMT. 
 
	We will let it run for awhile to see 
if everything looks good. 
 
NOTE: the 10m unit's fan was not housed properly. 
This must of been in this state for some time because 
it's bottle still had water in it. 
 
 

PSYC CONDITIONS: 
 
	The 4m wet bulb is reading too high and 
the 7m dry bulb looks low compared to the 10m psyc. 
We will let it run over night and hope for the best. 
 

When attempting to remove archive files, 
I was requested to override protection 664 
for each file.  The protection was -rw-rw-r. 
Shouldn't this have allowed me as aster to  
remove the files without quibling? 
 
 

IOP #4: 
 
	ARM went operational, along with WISP, 
at 18:00 GMT. 
 
	The system is up and running. 
Sensor status loooks ok except for the following: 
	7m tdry is reading low. I have Cathy checking 
the calibration coefficients. 
	The 4m Krypton is bad. This may have to do 
with water on the windows since it is raining out here. 
As a first pass, all other sensors are looking good. 
 
followup: 
	 The coeficients for the 7m psyc. are ok. 
Due to weather conditions, we will not be able to 
lower the tower to work on the sensor. 
 
	The 4m Krypton goes in and out. As mentioned 
before, this is probable due to the windows getting 
wet. 
 

WEATHER REPORT: 
 
	At the present time it is raining 
lightly, inside and outside the trailer! 
The link between the trailers is leaking. 
As a temporary fix some garbage bags will 
be taped over the boot. 
 

PYG TEMPS: 
 
	Charlie made the change to the parsing 
routine to accept the temperature coefficients. 
Xcockpit, covar, and xstrip have been re-compiled 
to accept the new preprocess routine with the correct 
parsing software. 
 

COVAR TASKS: 
 
	the covar tasks were restarted to use the new 
version of preprocess which allows for proper calibration 
of pyg temperatures. 
Also, they were started in root. 
 

SOIL SAMPLE: 
 
	A soil sample was taken at about 23:30 GMT. 
 

SONIC SPIKES: 
 
	The u component of the ncar.ati.comp 
sonic has been spiking throughout the day. 
The uw sonics have had a few spikes showing on 
the speed of sound computation. 
 

ANOTHER SCRIPT: 
 
	Graphpak is a combination of the 
basic graph packages we use. This way you only 
need to remember one script name but more input 
parameters. Below is the usage format. 
 
graphpak   wind <-s -d>> 
 
note: for psyc or wind you must add the extra parameters

Problems found with input data. 
 
 
 

COVAR RESTARTED: 
 
At 00:15, covar files were moved to .old, 
e.g. cosmos.covar -> cosmos.covar.old, and 
the covar processes were stopped and  
restarted.  The purpose was to allow writing 
cosmos.covar.old, etc. to tape and removing 
them from the disk.  The three .covar.old files 
take up 33.8 megabytes or about 5.5% of /home. 
 
 

Dropped psychrometer tower at 22:30 
to work on 4m wet bulb and 7m dry 
bulb.  Tower back up at 23:30. 
 
Steve found that the 7m dry bulb  
extended below the shield that separates 
the wet and dry bulb and that the dry 
bulb was getting wet.  The wick on the 
4m wet bulb was too short. 
 
 

Leaving for dinner in Platteville. 
 
 

SODAR AUTO PRINT ON 
 
Enabled auto print mode on sodar 
at 01:37. 
 
 

Back from dinner. 
 
ASTER processes all seem normal and 
cockpit displays look okay. 
 
 

NEW SCRIPTS FOR SONIC COMPARISON 
 
Wrote two new scripts for plotting the 
4m sonic means and covariances for 24 hrs, 
sonics_mean and sonics_cov.  They are 
used as 
sonics_mean    
and  
sonics_cov    
 
 

Status report at 03:00 
 
Checked wind, temp and cockpit displays. 
Vaisalla and Rotronics have different grey traces over the last 
few hours. The humidity at the site is varying quite a bit. 
PSP.in is not showing on the trace. 
Cannot graph the means. No match. 
 
 
 

Status report at 04:30 
Winds look alright, possible 7m Tdry is low  
psp.in is not showing and rh vaisala comp and rotronics show excursions. 
 

Status at 07:00 
Winds picking up, a bit of spiking on ncar.comp sonic, minor. 
The minimum in the Tdry at 7m looks natural 
psp.in back on scale 
Pitch and roll giving sinusoidal signal, much slower than frequency of tower 
Data system OK 
 
 

Status at 9:30 
cannot graph compwt 64 or graph_mean 64 u - all other graphs for JD 64 ok 
the error message is as follows for graph_mean 64 u  
 
Error in file `/tmp/graph_mean.25783' at line 807: 
  Cannot read second coordinate 
Problems found with input data. 
 
error message for compwt 64 :  
Problems found with input data. 
 
u.ncar.comp still spiking ( showing up on c.ncar.comp also ) 
 
warming up slightly but twet still frozen - tracking tdry 
 
 

NCAR ati sonic  
the u comp of the ncar ati sonic stopped spiking sometime between 9:30  
and 10:00. 
 
 
 
 

Status at 12:00 
most everything looks ok on winds, temps, cockpit etc. 
The pitch and roll of the 4m uw sonic are still showiing 
a slight sine wave shape - much less than a few hours ago. 
The 1m, 4m, and 7m twet bulbs have been thawing and freezing. 
 

Daily ops 
the pitch and roll were switched from the 10m sonic 
to the 4m sonic at 1:00, and the soil sample was taken. 
 
 

REPLACEMENT ROTRONIC: 
 
	The rotronic sensor being 
used in the humidity comparison was 
removed and a new was put in. The old 
one was known to act funny at high 
humidity. This was done at 20:45 GMT. 
 

Psycrometer errors 
The 7m psyc tdry is colder than the 10m tdry throughout 
most of the day/night. Possibly a moisture problem. 
 
 
 
 

Status at 2:30 
everything looks pretty much ok, the wet bulb on the 7m 
psyc has again thawed. 
 
 

STATUS: 
 
	System has been running very good for the 
last few hours. All sensors are running and giving 
good data. The psychrometers have their usual wet bulb 
problems at temps below zero. 
 

IOP #4 END: 
 
	IOP #4 ended at 01:00 GMT (066). 
 

ARCHIVE TASKS: 
 
	The archive tasks were restarted because 
they were last started under root which asks each 
time you wish to delete a file. 
 

Level change 
 
Levels changed 11:45 7 March 91 
From 4 m to 10 m 
 

Status report 12:00, 7 March 1991 
 
Wet bulbs are frozen, spiking throughout the night on NCAR ATI, a bit 
of spiking on the Gill 
 
 

Soil samples Depth profile taken at 11:50, 7 March 1991 
 
 

SODAR BACKUP: 
 
	The sodar backup was perfomed around 
21:00 GMT. 
 

Status report 16:30, 7 Mar 91 
 
No problems apparent. 
 
 

Forgot to kill archive files, file system 
full from 0355 to 0635, so raw data was lost 
for this time period on jd 067. 
 
 

REMOTE STATUS: 
 
	Logging into aster from Boulder, the 
system is up and running. Temps and winds look 
ok. 
 

NEW GRAPH ROUTINES: 
 
	Over the last week a variety of 
new scripts have been written to do graphs. 
Below is a discription of some of those routines. 
 
GRAPHPAK: graphpak was designed to combine a number 
of the standard graphic packages we use. These are 
graph_rad, graph_ts, graph_baro, compsyc, and compwind. 
The input string to the graphpak is the same format as 
has been used for the other routines above. The only 
difference is you have to tell it what you want to 
plot. 
 
USAGE: graphpak   wind <-s -d>> 
 
EXAMPLES: "graphpak 67 psyc -w"    "graphpak 63 baro" 
 
note: for psyc and wind, you must add the additional parameter. 
 
 
 
XYCOS, XYRAG, XYMAR: These packages provide xy plots of any 
parameter coming in on their respective ADAM. The switches 
available let you do differences vs one parameter or time, 
simple x vs y, and one parameter vs time. 
 
USAGE: xycos    <-d -dt> 
 
EXAMPLES: "xymar 66 pyg.in.rad pyg.out.rad -dt" 
	  "xyrag 54 u.4m.uw null" 
 
notes:  parm1 and parm2 are the x and y components. The 
	proper input string is the "did" configuration 
	name. As an example, for the 4m Krypton sensor the 
	input string would be: q_h2o_uv.4m.uw 
	if null is used as the second parameter, a time 
	series plot of parm1 results. 
	Switches -d or -dt are optional, if not used the 
	plot is parm1 vs parm2. 
	switch -d: parm1-parm2 vs parm1 
	switch -dt: parm1-parm2 vs time 
 
 
PLOTQ: plotq is a special package for comparison 
plots between the Krypton sensors and the Vaisala 
sensor at the 4m height. The format for this script 
is similar to the xy scripts. Only one input parameter 
is required, y. the x component is defaulted to the 
vaisala component. If you want a plot of the krpton at 
4m vs 10m, use xyrag. 
 
USAGE: plotq   <-d -dt> 
 
EXAMPLE: "plotq 23 q.4m"    "plotq 45 q.10m -dt" 
 
notes: parm possibilities are "q.4m" and "q.10m". 
 

SENSOR STATUS: 
 
	All sensors looking good except for 
the ncar ati sonic. there were a few spikes 
during the night. 
 

TDRY.7m: 
 
	The tdry sensor at 7m is reading lower 
then the 10m sensor. The question is which one is 
at fault. Since we had problems with the 7m unit 
before it is the likely choose. However, after watching 
xstrip for awhile, it appears that the 10m sensor is not 
responding the same as the 7m and 4m. We will try to lower 
the tower today to do some servicing on it. 
 
update: As discovered before, the fan may be our problem 
at 10m. It may have slipped out again. 
 

Soil sample taken at 14:00, 8 Mar 91 
 
 

Status check at 15:00, 8 Mar 91 
Everything look alright except possibly the 10 m Tdry 
Just a few spikes on NCAR comp 
 
 

Status at 19:30 , 8 Mar 91 
 
Backup finished, no apparent problems 
with any of the sensors or systems except: 
 The sodar which was not printing out this afternoon. 
     I restarted it at approx 17:30 
     I switched on the printer and recycled the computor and the monitor. 
 The 10 m Tdry which still appears to be out of line with the others of the 
     profile. 
 

Cleaned up bad entry in marigold.covar.067 
associated with the break in data archiving 
between 0400 and 0630. 
 
 

Everything looks hunky-dory @10:35. 
One spike on NCAR ati. 
 
 

Possible errors in covar files. 
 
At ~5:40 I cleaned up an error in 
marigold.covar from day 067. 
I did this between the 5 min writes 
to the covar files, but the size of 
the file also generated a 'device 
full' warning during the editing 
process.  Perhaps this introduced  
another error in the covar file while 
I was cleaning it up.  I just tried 
to run comp_uv10m 68 and it bombed, 
possibly while running covar_split. 
 
 

ati channel v shows strange behavior, possibly 
related to the cold temperatures. Seems 
to have a low frequency drift. 
 
 

twet at 10m is dry 
 

twet at 10m is wet again 
 
 

I regenerated missing pieces of marigold.covar 
from the archive files. Note that for jd067  
the time tags are out of order; should not 
bother shocov though. 
 

4m propvane is out 
 

STATUS for jd 70: 
 
	System is up and running. The 4m 
prop is not responding, will try recycling power. 
The uw sonics had a few spikes over the night. 
The ncar ati had quite a few more. The other 
sonics looked ok. 
The 10m tdry still looks high. Depending on 
available people, may lower the mast today. 
 

PROP 4m: 
 
	The 4m prop would not come back 
to life after recycling power. Therefore, 
it was replaced with sensor #6. The direction 
was set the same as the 4m, 326.06. The pitch 
is 292. This was completed a few minutes ago. 
 

SOIL SAMPLE: 
 
	Soil sample taken at 18:35 GMT. 
 

LEVEL CHANGE: 
 
	The level sensor signals were changed 
from 10m to 4m at 18:40 GMT. 
 

RAGWORT- analog channel test: 
 
	From 20:10 to 20:40 GMT, the analog 
channels on ragwort were being checked with 
a voltage source. 
 

RAIN: 
 
	It has started to rain here! 
 

IOP #6: 
 
	This IOP started at 21:00 GMT. It is a 
WISP IOP inwhich ARM will participate. 
The sodar printer was started. 
 

PROP- 10m: 
 
	The 10m prop wind speed has shut down. This 
occurred about 10 minutes ago, 21:00 GMT. Direction 
information is still coming in. At this time I have no 
clue as to why. 
 

COVAR_MARIGOLD: 
 
	Covar_marigold was restarted since it 
was not writing any data to the file. It stop 
writing to this file back on day 68. 
 

PSYC TOWER: 
 
	The psyc. tower was brought down 
to work on the 10m unit. The fan was ajar. 
After fixing and filling bottles the tower 
was backup at 22:10 GMT. Tower came down 
at 21:45 GMT. 
 

Sonic status: 
 
10m uw sonic had a few spikes evident on the 
speed of sound output.  NCAR ati on the u component 
(and speed of sound). 
 
 

High winds and rain. 
 
Spikes on the Gill and NCAR ati since 
the last time cockpit was cleared. 
 
 

Strong westerly winds and moderate rain. 
A good test for the sonics. 
 
The Krypton hygrometers do not like 
the rain.  The v component and the 
speed of sound have gone off scale 
on the NCAR ati. Some spiking on the 
ati.comp and on the uw's.  The gill 
looks clean. 
 
 

Reconstructed marigold.covar's for 
JD's 68, 69, 70, but not the root 
marigold.covar.   
 
 

Operations at 00:00 local time 
winds are gusting to 20 m/s , light snow is falling. 
u.ncar.comp 
u.4m.uw 
u.10m.uw all seem to have lots of spikes 
10m anemometer is down (speed only - direction ok) 
 
 

Status at 4:30 A.M. local 
All processes are up and running. 
Wind speed has fallen off a bit, 
still gusting to about 16 m/s. 
Light snow did not last long. 
 u.ati.comp   slight spiking 
 u.nccar.comp  lots of spiking 
 u.4m.uw 
 v.4m.uw both look like lots of spiking  
but it is not present on c.4m.uw ??? 
 u.10m.uw 
 v.10m.uw are both noisey ( is evident on 
c.10m.uw ) 
10m anemometer is still down ( no speed ) 
 
 

STATUS 13:30 GMT: 
 
	System is up and running. Sensors 
look good except for 10m prop. 
Spiking on the ncar ati u component. 
 

RH ROTRONIC: 
 
	The rotronic rh response went to 
100 % at about 7:00 GMT and has not come back 
down. The vaisala has a similar response but it 
comes back down. 
 
Follow-up: Upon examination, the rotronic has lost 
its transducer. This may have been the result of high 
winds last night or the airflow from the fan. The 
transducer did not have its filter cover on. 
 

SOIL SAMPLE: 
 
	A soil sample was taken around 19:00 GMT. 
 

LEVEL CAHNGE: 
 
	The levels were changed from 4m to 10m 
at 19:05 GMT. 
 

TAPE DRIVE: 
 
	The tape drive did not want to initialize 
a tape. I had to recycle power to get it to work. 
2 tapes were initialized. 
 

STATUS UPDATE: 
 
	System running with no problems. 
The ncar ati has a number of spikes. Spikes 
also appear on the 4m uw sonic, v and u components. 
There are a few spikes on the 10m speed of sound. 
The 10m wind speed is still out. 
Also, the rotronic intercomparison unit. 
 

END OF IOP#6: 
 
	IOP #6 ended at 21:00 GMT. 
System was running with the same problems: 
spiking on ncar ati, no 10m prop speed, and 
a few spikes on uw sonics. 
 

SODAR work: 
 
	The sodar printer was stopped and the 
data backed up on floppy. 
 

COMPUTING RH from PSYC: 
 
	Found mistake in psyhum code which 
computes rh from tdry,twet. Will run some plots 
on vaisala/rotronic comparison units. 
 

STATUS: 
 
	System up and running. There were a few 
spikes, throughtout the night, on the uw sonics. 
The ncar ati had a lot. The 10m prop speed is still 
down. So is the rotronic comparison sensor.` 
 

RAGWORT INGEST SHUTDOWN: 
 
	Ragwort ingest shutdown a few minutes 
ago. Error message refers to: INGEST_SOCKET_ZERO_READ 
for ragwort. I logged into ragwort and everything looked ok. 
Ragwort proceeded to spit out bad time tag messages from recDatel. 
Ragwort was back up and archiving at 20:16 GMT. 
 
followup: Forgot to "data_on" ragwort; therefore, data collection 
didn't start until 20:35 GMT. 
 

GRAPH_COV error: 
 
	Graph_cov did not want to work for 
"u w" and "v w". Error meesage refers to a 
temp. file inwhich second coordinate could not 
be read. 
 

SOIL SAMPLE: 
 
	Soil sample taken at 20:45 GMT. 
 

LEVEL CHANGE: 
 
	The level signals were changed, at 20:50 GMT, 
from 10m to 4m. 
 

7m wind speed & direction plot 
 
I modified the Splus wind speed and 
direction plotting routine to alternately 
plot the 7m winds rather than the 10m. 
This is invoked with the optional input  
variable, altprop=T, e.g.: 
 
fun.winds("prop#070",altprop=T) 
 
 

PROP - 10m: 
 
	The 10m prop was removed at about 21:30 GMT. 
The problem was in the 4490 debounce switch used for speed 
pulses. The sensor was repaired and installed at 22:30 GMT. 
 
 

zo analysis 
 
I've fitted several "near-neutral" cases for zo (all 1 hour long): 
using displacement heights: 
 
Day Beg Dir zo  err disp  z/L 
            cm  cm/s cm 
48  16  163 4.7 1.0  10 -0.015 
55  17.5 18 2.6 2.1  20 -0.025 
56  22  338 2.4 0.8  20 -0.011

73  21  140 3.2 2.1  20 -0.085 
 
Obviously, a good value for zo for northerly cases is 3cm and disp=20cm. 
Also, other directions are different.
