IHOP02: Site 1 Messages, 23 Entries..

06/24/02  9:55 - 10:15 Local

Purpose: Steve went to the west early today for the
	Final Trime Soil Measurement.

Cleaned RAD/Kh2o
	minimal dirty.  We suspect the particles are so dry and the
	winds so strong the domes stay clean.

RainGauge: had 2 old (blind?) mice in the top but they didn't seem
	to be bothering the bucket.

Trime measurements:

ISFF:   12.7
P7:	9.8
P11:	13.4
P5:	12.1

06/21/02 08:00-12:45 Local
TWH:  I think this should be 6/22/02 08:00-12:45

Purpose: Finish work begun last night: Tsfc, etc.

Station still running OK.

Tsfc:	Down/bad overnight however it began reporting
	good data just before or as I arrived.
	Ran with spare irt and cable for awhile to make
	sure that was working.
	Licor channels on same SOAD are OK, and have been,
	which indicates the cabling/etc.for the IRT. Recleaned
	and checked cables.  Found somewhat loose +v wire on
	the plug into EVE Front Panel.  That appears to have
	been the problem and when I was working on the GOES,
	must have jostled it just enough...  Didn't replace
	sensor or cable as a result.

SoilHF:	Came in overnight and appears reasonable.
CS615:	Steve reports was varying normally but it has a high offset
	now for some reason.  Didn't / couldn't replace it.

Site Tilled Today
	The farmer was discing the ground last night and continued
	today.   I expect that by ~2pm local he should have completed
	everything within 100yds to the south (and all around) the
	station.
	At ~10:15 he took the closest turn around the site and I
	helped him till the section where the a/c cable is.

Cleaned Rad/Kh2o at about 10:35.  There wasn't much dust despite
	plowing.  h2oV went from ~370 to 410mV.
Trh filter Checked.  It has a small amount of visible dirt but nothing
	unusual nor more than what's on the spare in the van: left it.

Soil under Sawhorse 'Normalized' by ~12:15 local
	I hoed the weeds, chopping up the ground to make it appear
	like the field is now out to about 7m from the rads.

06/21 18:45-20:45 Local

Purpose: Station was not reporting over GOES.

Station was running OK, i.e. it was not down, just the goes.

Goes:	No comm w/EVE.
	Turned out to be bad power connection from front panel.
	Swapped in new cable, but it seems that the socket on the
	front panel is the real culprit.  Moved serializer power to
	'baro' plug and goes to 'freewave' due to lack of sockets on
	this panel.  It appears this panel needs some work.

SDR HR:	Swapped, #6 in, #4 out

Tsfc:	Problem, reporting bad values.
	This has happened here before at this site, but it had been
	working prior to the 'goes outage.'
	I noticed bad values and Steve confirmed.  The Amp-9 connector
	had corrosion; cleaned it.  Tried a spare sensor and that worked.
	It was getting too late to lower the mast so decided to return
	in the morning.

Soil Sensors: SoilHF was down due to chewed cable.  I was only able
	to strip the wires, twist them together and tape the mess.
	The values metered at the box were suspiciouly low (as in
	bad).
	CS615 has been reading high: 70% volume, whereas the profiles
	are showing in 10-20% range.  There didn't appear anything
	wrong with the cabling or internal wires except the cable
	coming out of the connector was pulled a bit.  I tried to
	improve that but it didn't help.

06/19/02 09:30 - 10:10 Local

Reason:	Double check station was ok, swap sdr

SDR Microdrive #6 was removed, #4 installed.
backup_sdr was run at the base later.

Checked gas cylinders and decided to swap in new N2 based
upon usage over the last couple of weeks.

N2	2700	6.5"   (old had been 500 /6")

06/18/02 18:45 - 19:50 Local

Reason:	No messages coming in

Station was operational, power was ok, SDR was running, etc.
Downloaded metppf.

GOES problem:
The unit was 'dead' and eve couldn't talk to it.  The front-panel
power plug may have been 'bad'.   When measuring the power it
appeared to be low, then ok.  Perhaps it was loose but I tried
to wiggle it around quite a bit to reproduce this problem and
couldn't.
After getting power back to the transmitter, I could program
it normally.  However the output power was very low: 3W.
Replaced GOES:
Out:	015 	this one is bad!
In:	1002	this one was swapped from site 2 a few days ago
	and may be bad because that site had been dropping out
	with questionable goes rf during the middle of the day,
	however, it's forward was 15W (yeow!), ref=1W (hmm)
After that the station has been coming in.

6/17/02 16:25-50 Local

SDR_OEM Swapped
	#3 Removed 
	#6 Installed
	#4 Left inside Elect. box

Metppf Copied to Panasonic.
GOES time OK

Krypton Cleaned: 16:25

Rad Cleaned / NetRad Level Checked: 16:40

Checked Cal Gases: OK
The N2 cylinder is the only one which might run out before the end
of the project.

SEE ALSO: Note about EVE file-system problem

6/17/02 !6:20-50 Local

During Site visit, upon arrival, we noticed that the EVE file system
had crashed.  Nevertheless data collection / goes was running OK.

The evidence of this is file-size =0 for all files when doing a 'dir'
command for either the ramdisk or /card.
Upon checking the syslog file I saw many entries indicating 'metppf
file access fail' for the 5-minute writes after the crash.
Unfortunately I managed to lose this syslog file.
When eve booted up it copied that existing, full syslog
file to the card and started a new syslog as expected.
My problem may have occured when doing the move_metppf script
on the panasonic when I abnormally exited using a ctrl-c.  It appears
somewhere along the line an old version syslog file was copied and
tagged for the 6/17 dated version.

The EVE file-system problem was recovered by the power cycle as expected.

Keep an eye on Sta-1.  This has happened before in my recollection
and appears due to a timing conflict during operations of a 'fast-save'
station which is heavily loaded and doing the regular 'metppf' saves
to ramdisk.

EVE TO-DO NOTE:
This type of file-system error should initiate a 'reboot' assuming
that'll recover this problem.

13 Jun''02 Trip to the Western sites
Water in the field. Walked into the site

Arrived 14:05
Switched the microdrive discs. Removed #1 (04/02) and installed #3. Left #6
  atop the VME cage as a spare.
Panasonic powered up but low battery failure. Attempted to run on spare PAM
 battery in van via the DC  charger but could not get to run.
 (Later at base discovered that the DC charger voltage regulator box was dead)
Could not communicate with station.

14:48 cleaned Kr
14:50 cleaned radiometer domes. Noted spider perched atop K&Z sw.in

CO2 gas cylinders:
                  2000.5.8
                  1850/5.5
                  1960/6.0
                  2000/5.0
             N2   1180/6.0

Departed 15:00

Arrive: 0838
[reinstalled soil profile wiring]
- CR10 had been running the radiation calibration code since we left yesterday,
  though I thought I had changed it.
- Checked CO2 cal gases at 0848:
	1/1: 1930/6.2
	1/2: 1730/6.0
	1/3: 1890/6.1
	1/4: 1890/6.9
	 N2: 1700/6.2
- Reinstalled soil profile wiring 
- Restarted normal program (*4 99 = 0)
Depart: 0917

Arrived 14:44
[ongoing boxing of krypton electronics; fix of soil profile 5; start radiometer
calibrations]
All ventilator fans operating except LW.out. Power disconnected for vent fans
Gas cylinders fro the north:
     1/1   2030 psi/5.5 psi
     1/2   1850 psi/5.5 psi
     1/3   2000 psi/ 6.0 psi
415.7 ppm  2000 psi/ 5.0 psi
 Nitrogen  1850 psi/ 6.0 psi
     Capped N2
Another capped cylinder of N2 was laying out of the array.

14:55 opened Kr electronics box: no corrosion. Remounted inside plastic box
 on sonic side of the mast.

15:33 SDR 3 -> 6

Checked power from chem shelter: 12.23 volt

15:38 cleaned all radiometers, they appeared to have been OK

15:41 cleaned Kr windows

From 16:00 to 17:15 investigated the problem of the bad/missing data for the
profile 5 = P3 . Eventually discoverd bad corrosion in male connector at 
logger.  All three connectors had corrosion and the wiring was removed for 
cleaning this evening at the motel.

From 17:15 to 17:35, the sun block by disc was done for the radiometers.
The logger was set to allow fast data to be collected.  Found during call
to Steve Semmer that Tdome and Tcase were scaled incorrectly.  Decided to
take data with just voltage output from these by changing all coefficients
to 0,1,0,0,0.  Captured to s1l.020606
After the test the logger was programmed to its normal mode. [PS: WRONG!?]

Checked that clamp holding mast was secure.

Depart 17:44 

Arrived 13:14 after driving from Wichita

Clean Kr at 13:21

The down-looking SW had been giving problems but showed no obvious reasons.
 !3:35 - 13:45 removed K&Z 970380 and installed K&Z 940181. Did not change
 Campbell coefficients
 
14:00 - 14:10 tightened all screws of radstand Campbell barrier strips

!3:50 took two "clods" of soil. Not very cohesive with 1 -2 cm crust and damp
  uncosolidated soil underneath containing lots of crop residue.

Steve tightened all screws in soil multiplexer and separated the soil profile 
 shields and grounded them separately to the signal grounds

Steve shielded the EVE power and serializer  cables. Before shielding
 Kr = 250mv and Tsurf = 0 and afterwards was small.

Captured s1.02 06:01

Downloaded /card and replaced SDR #6 with SDR #3 and left SDR #4 in the bag.
 Bag now has SDR#1 and SDR#4

Departed 14:50       

Departed at 14:50

Josh just called to let us know that he is at site 1 and has just tightened all the terminal block screws in our logger box.  He said that two "purple wires"
were at bit loose.  We'll have to see if this improves the Rsw.out data.

P.S. The data from Rsw.out is even worse now.  Thus, this fix did not work.  The
next step apparently is to swap out radiometers.  (We brought spares with us,
but might not have calibrations for them -- I'll have to check this.)

This site had one 12V power supply for all systems:
	EVE & sensors, CO2 pumps, valves and CO2 data system.

Since we're seeing low voltage at the campbell boxes (11.2V) at this
site (and site 8) we'll try adding a power supply and see if that
helps the soil profiles.  

A white 4x8x3 inch power supply (5A?), is in a cooler at
the mast along with a battery. 

EVE, power supply and the battery are all wired in
parallel, using a multi-branch power cable.

An extension cord runs back to the chem shelter.
We're using the outlet on the transformer that the chem shelter
air conditioner was on.  The air conditioner is now off - Kurt 
doesn't think it is necessary to cool the transformer. 
Bring an outlet strip if you want to power up the AC.

This switch was possible without powering down the CO2 system.

Finished at about 18:00 CDT.

We're now seeing 13.8V at EVE and 13.2 at the campbell boxes.

May 22

Tom opened up kryton box (SN 1395), cleaned connections on
power/analog-out connector with contact cleaner.

This one had oxidation, but no loose chunks like several others.

Cleaned head with distilled water & Qtip at approx 16:50 CDT

Site visit, May 22, 16:40 CDT

Replaced EVE EPROM (won't print console mesage on non-zero CSAT diags)
	old: EVE 4/21/02 6047
	new IHOP02 5/14/02 0xA7BA

Downloaded slow data.

Removed microdrive #2
Inserted #3.
Left #1 and #6 inside EVE box.

Krypton had slight oxidation, see entry 116

Voltage at soil profile multiplexer and campbell logger: 11.2V

Installed new power supply & battery, see entry #117, which brought 
voltage up to 13.2V at Campbell boxes, and 13.8V at EVE.

Nitrogen: 425 PSI (Scott called and will try to have that cylinder
replaced this weekend).

Left around  18:30

Morning of May 12, site visit to station 1:

These are the microdrives at station 1:

#2 XHAN4374 05B cleared, in eve box
#3 XHAZ2739 09B cleared, in eve box
#4 XHA75885 99B inserted in SDR

Drove to ISS site, and back to stn1 with Bill Brown.
Showed Bill how to swap microdrives.

The archive at stn1 is 40 Mbyte/day, so we can get
a week on a 340 Mbyte microdrive.  Asked Bill to
do the swap on Saturdays

df -H reports the microdrives at 358 Mbyte (M=1000000, not 1024x1024)

Morning of May 12, site visit to station 1:


Replaced slow A/D on 9:15 CDT

	old unit:  EVEAD 05,93 A1  4/19/02
	new:  EVEAD 09,93 5/6/02
 

Site 1 visit, May 11   John and Gordon

Lowered mast to swap everest.

Swapped in new everest, no change. Tried new cable, no change.
Problem of bad Tsfc was actually the slow ad.  It was running,
but all quantities, Tsfc, Plicor, Tlicor, Qlicor were constant,
bad values.

After cycling power on slow ad the data came back.  Will
watch it tonight and perhaps swap in a new a/d tomorrow
morning.
 
Swapped in new krypton: 1395 to replace 1101:

	1101:  1.31V, -6.09 gm/m^3
	1395   0.375, 13.3 gm/m^2

Shot boom angles with KVH (7.5 E declination)
  sonic 268.8
  prop  177   Old BD was 184, changed it to 177! 7 degrees different!
      (Note original sonic direction was 99+180=279, 10 deg different.
       This suggests that the original angles were magnetic. TWH) 
  rad stand   93.4

checked rad coefficients:
  One wrong coefficient:
	KZ-940186  PSPIN  04  was 80.257, changed to 82.988
	(also coefficient 53) 
        (See logbook entry 14 for pre-project coefficients. TWH)

installed new krypton cal
downloaded slow data
downloaded fast data from SDR microdrive
Fast data files were being created every 1/2 hour.
John fixed SDR config so that file creation is under control of EVE,
not SDR:
	entersys, talk to SDR
	CR gives menu
	#7 File system options
	#8 set file closure schedule  set it to NO

	
swapped SDR microdrive

trim readings:
%vol	TDR
8.6	48	loose (plowed - actually spaded)
18.6	36	packed (not plowed)
11.3	42	loose (plowed - actually spaded)

TWH: It appears from the sonic data that the mast was lowered 
     from 23:20 - 23:55 GMT.

Finished setting up site one. John found a faulty
barometer that was causing problems on the SBUS.
  Kurt had to make some mechanical changes to the tripod
in order for the wench tool to work correctly.
He also took care of the AC power.
  The radiation stand was moved from its original
placement yesterday. It was moved ~7 meters to the
west. It is now overlooking plowed soil. The profile
boxes are to the east. Profile 2, box 5, is due east ~8
meters. Profile 0, box 11, is northeast ~3 meters. Profile
1, box 7, is southeast ~3 meters. Time was spent shoveling the
soil near the darkhorse to get it representative of the
site. It is recommended that the same thing be done to the
remaining soil around the profile boxes.
  The rain gauge was installed in the middle of the triangle
created by the profile boxes.
 

Started setting station 1 up late in the day.
The tripod and radiation stand are up. Tomorrow
we will finish the installation. Information for
today.

EVE will be applying a fixed sample lag prior to computing
covariances between the sonic winds and the fast co2 data.

This is necessary because it takes a second or two for air to
travel down the tube from the sonic to the Licor. 

Tony plans to estimate this lag by doing correlation vs lag
analysis of (the recently completed) FLOSS project data, and
scale the lag by the ratio of the tubing length at IHOP and
FLOSS (assumes that we can get approximately equal flow rates).

The CO2 lag time should be subtracted from the time tags of the
co2 samples,then re-match the CO2 samples against a buffer of sonic winds
before computing covariances.

The high-rate data is being saved on compact flash at the stations
with a CO2 sensor, so we can do correlation vs lag analysis on the
IHOP data, and apply corrected lags (possibly time-varying) for 
the final dataset. Note that this won't occur in real-time - at best
a week later.

The pertinent EVE configuration lines are 
(this example shows a lag of 2.5 secs):

SYNC: Sync20 20Hz
SONIC.U
SONIC.V
SONIC.W
SONIC.co2 DELAY=2.5

To check things, John created an EVE 
config which created a co2 value equal to the sonic tc, then applied the
lag before computing the wind-co2 covariances. The high rate data was 
also saved, and the data were passed through the ASTER covar process
and the results compared.  

The attached plot of simulated w'co2' 
computed on EVE and ASTER shows the agreement:  w'tc'.s2a is the
ASTER covariance computed with a phase entry in prep.config of:

  p=2.50 f=none d=(tc).s2a

I verified in the aster processing that the phase value is SUBTRACTED from
the time tags of the given variables.  Since the data match quite closely
(and zero lags and lags of the reverse sign don't) we can assume that EVE
is also SUBTRACTING the above delay value to the time tags of the wind.
John has verified that in the EVE code.
