IHOP02: Site_visit Messages: 135 Entries..

Logbook entry made post project using information from my paper logbook.

Arrived site 8 at 16:50
Mast down at 17:02
Replaced bearing assembly of propvane at site 8 with the bearing assembly of 
the spare. Kept same vertical assembly and prop.

Bad fan of LW.out replaced with equivalent 7 bladed Nidec

17:43 microcard swap, 5 out, 2 in.

This entry was made post-project from information in my paper logbook.

Arrived 15:03
Primary concern was the GOES interference.
GOES DCP 120 inside Eve box. Shielded both Tsurf and Kr cables with foil.
Comparison of Kr signal prior and post shielding indicated that shielding helped

06/23/02 15:35-16:25 Local

Purpose: check Krypton mount, shoot boom angle, sdr start

Krypton: Steve wanted to make sure the mounting was correct.
	It's exactly the same as at site 8: vertical orientation
	on the north side of the UW aligned back from the sonic
	sampling area, basically where the main support boom begins.

Alignments:
	UW:	272.4 degrees looking towards the sonic/station
	RMY:	184.0 degrees

Move_metppf done

SDR Started: see entry #265 for more.
	NOTE I had quite a bit of trouble downloading/uploading
	the modified config.dat using the flashdisk.  Several
	false file-system entries and a couple of bad file writes.
	Could indicate a problem with the pcmcia drive of this
	(new) 16mb flash.

06/23/02 14:15-14:40 Local

SDR swapped 19:23z: #1 out, #4 in

GOES note: Just like at st7 the power plug was loose in
	the socket, no doubt due to opening the door.
	Although the cable is plenty long, it has a shield
	on it which again was apparently enough to cause the
	plug to unseat.  Fortunately this time it did cause
	an outage although perhaps this may have something to
	do with our occassional dropouts because if the xmtr
	sees a voltage drop when it powers up, it cancels the
	message.
	This has now been a problem at st1,7,8 ....

06/23/02 11:45-13:40 Local

Purpose: No GOES messages coming in.

The station was actually up and running OK.

GOES:	Another power plug problem!
	The power plug was slightly ajar.
	It seems that the shield on this cable
	stiffened it enough so that opening
	the door caused it to disconnect even though
	it appears as if it was still in the front-
	panel socket.

SDR:	The error LED was flashing indicating the recorder failed.
	(This unit has been a problem child.)
	Removed microDrive #2 files copied covering ~24 hours for 6/21.
	(see entry #265 for more)

	Replaced button battery so date/time/etc. will stay put.
	Moved unit to 'pin-jack' method so it can be used without
	power cycling EVE.
	Swapped code to version 7.3.
	Installed microDrive #5 and restarted, but...

	NOTE: The drive is making noise continuously so it'll
	probably die.  This older version of the sdr board/code
	leaves the drive running so it's more vulnerable to problems.
	Need to make the upgrade to the newest version.

RAD Cleaned ~17:10z
Move_metppf done

  Visit to 9:
   Replace K probe sonic with UW. Boom angle with compass: 91 degrees
The krypton was mounted on the north side in a vertical position.
It may need to be moved in toward the sonic boom. This will be checked today.
  Cleaned the krypton and rad domes.
  Install the SDR system. Did not start up because changes need to
be made to the config file and I did not have the information.
 

Went to station 7 to get the SDR communication cable.
Also cleaned Krypton.
I apparently did something wrong because the station went down.
Will fix today!

Remove SDR unit to install at station 9

06/22 17:45-18:35 Local

Purpose: Check RG, SDR start

Rain Gauge: Steve's little friends returned. I once again ruthlessly
	sent them off and tried to put some alum.foil underneath to
	prevent their return.
	The chewed wire was fixed/improved.
Many False Tips:  While poking the little buggers they danced back
	and forth over the bucket and then I did a 10-tip test
	Test at 18:06 reported at 18:14:20.

SDR Bummer: Darnit I plugged the SDR into +batt adjacent to +5 on
	the power supply by mistake and it appears to have been damaged.
	Tried removing battery, swapping hc11, etc. to no avail.
	It may be a simple cheap fix, but we're down to 4 for the
	rest of the project.
	At least the microDrive was still working per the panasonic.

06/22 13:45-14:05 Local

SDR Test Stopped  See entry 265 for times.

Move_metppf

Left 'fastout' config running rather than stop/start

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.

06/21 17:20-17:45 Local

Purpose: Install SDR
	Check RainGauge

Rain Gauge: It was OK, and level; ie no mice (but then again
	I'd bet there are many snakes guarding this site!)

SDR Test initiated: Shield On.  See entry 265 for times.

06/21 13:55 - 14:10 Local

SDR Test ended.  17:30 hours long.  See entry 265 for times.

06/21 12:05-14:45 Local

Purpose: Check RF/pwr, clean sensors, cut wheat, Install SDR
	Check RainGauge, soil sensors.

Site Maintenance:  Weed-Whacked the wheat to match the field
	appearance now that it's been harvested. 

Rain Gauge: Had an abandoned mouse nest.

Soil Sensors: Tightened connectors for tsoil 5, gsoil6 on profile.

Krypton: Cleaned; before ~65mV after ~170mV.
	Also verified s/n 1101 and file coefficients.

Goes:	Antenna was pointing down at an inappropriate angle. This
	may have been cause of drop-outs.  Realigned it and also
	installed a 3rd battery for the station.

SDR Test initiated: Shield On.  See entry 265 for times.

Move_metppf done.

EVE Problem:
	2 spurious reboots occurred while we were here.  They
	maay have been something to do with the SDR / cabling but
	that's definitely not certain.  The watchdog did restart
	things and then it seemed OK.  Did not swap cpu/etc.

A quick trip to 9 to install a new electric fence charger.

  I went by station 7 to check on the SDR system to see if the changes
made yesterday worked. Based on the filenames and sizes, everything looks
good. Below are the filenames and size
filename	created		size (bytes)
06202151.00Z	00:51:12	12045610
06202152.00Z	08:51:16	12060324
06202153.00Z	16:27:12	11090682
06202154.00Z	16:27:12	322033

The last file was created after I stopped data collection to examine
the filenames.

  At 7 the flashcard in the SDR was removed and replaced with another
larger capacity card. The configuration parameters of the SDR were 
checked and the filename was changed to a more representative name.
  There were not mice or nest in the rain gauge.

Note About SDR files:
	They were once again short files.
 ls -l /mnt/pccard
-rwxr-xr-x    1 pam      rtf             0 Jan  1  2011 041912ao.00z

-rwxr-xr-x    1 pam      rtf         60535 Jun 20 16:46 06180001.00z
	However Steve checked the configuration of the SDR-OEM
	and it was ok.  Perhaps that unit has a problem, or else
	the media (in this case one of the 192mB compact flash cards)
	was bad.
	The files were stored in,
	/aster_data/aster/projects/IHOP02/raw_data/sdr/s07

  On my way to 7 I stopped by 8 to see if we had any mice in the
rain guage. There was a nest but no one living there.

  I took a trip to 9 to do some repairs on the electric fence
and to replace the K probe sonic with a UW sonic.
  The fence had lost some insulators. This caused the fence charger
to go bad. There was no visible cattle damage.
  Unfortunately, the UW sonic was not fully assembled back in Boulder
so I was not able to install it.
  I did find a nest with 4 mice in the rain gauge.

06/20 16:35-17:15 Local

Purpose: Install SDR
	Check RainGauge because of suspicious tips/noise.

Rain Gauge: Had Mouse Did Travel!
	Naturally the little bugger immediately scurried
	up inside the sawhorse leg...
	I tried to put a bit of alum.foil in the bottom
	of the gauge to prevent a rodent return, but it
	probably won't work.
11 False Tips: Test during visit from 17:00-17:10.
	Note the logger definitely sent these 'late'
	I scrambled to make the tips just before the
	message was sent at 16:59:20.  The logger, processing
	at 5-sec. intervals reported 2 tips at 17:05, and
	9 at 17:10.

SDR Test initiated: Shield On.  See entry 265 for times.

Move_metppf done.

Cleaned Krypton 16:56 local
Cleaned Rad	17:09 Local (pyg.in was dirty, rnet seemed ok
		psp.in had a small bit)

06/20/02 13:25-15:25 Local

Purpose: ATI sonic has been reading higher than RMY
	Tom noticed this happened right after harvesting
	and speculates that the higher wheat under the
	site may be the culprit.

'Weeds' Whacked: I took photos before and after doing
	this.  Job done by ~14:30, including under the
	sawhorse.

SDR Removed: See entry 265 for dates of shield-on hr test

Checked metppf: OK
	I did this to see if the error shown in the syslog
	for site 3 was typical when putting the 'config.hrx'
	files on the ramdisk.

R.G. Checked: Mice have not returned, but the wires were
	chewed previously.  Tested:
	False Rain tips during entire period 14:50 - 15:30
	Total false tips = 17.

Logger Note: It appears that the logger doesn't send the
	rain tips in the same block as the time they were
	taken, but in the second message after that.

06/19/02 16:15 - 17:30 Local

Note:	The field has been harvested.
	Probably within the last 2 days based upon
	observing the harvesters working in the adjacent field
	to the east.

John and I met at station 6 to do a few things.
Based on comparison plots of wind speed from the central
sites, we decided that the sonic was having problems and
not the prop. So we lowered the mast and re-zeroed the 
sonic (input from Steve Oncley)...see below.

We also found a family of mice in the rain gauge. They
may have been the reason for false rain tips. There were
2 mice down in the space below the tipping bucket while 3
were playing around on the top near the funnel. We will check
stations 4 and 5 tomorrow to see if any other creatures are
housed in those rain guages.

Other items worth noting:
	The krypton was cleaned
	Boom angles were checked after raising the mask
		sonic: 85
		RMY: 175, RMY value was set to 176, we did not change it
	Shielding was added to the GOES power and RF cable
	Installed the SDR, #3, ST6_0619.dat (this will be the shield
test data set)

Went to station 7 to get the fast data. The 340 flash was
replaced with a 196 flash. We will need to change the 196
in a few days.
  I also cleaned the domes and the krypton.

Mode 4 memory space and Mode 3 program into this same file.  In normal logger
operation, the calibrated values looked okay.

Note, 7/23/02: This is consistent with logbook entry 44, Gordon did not
correct the PSP coefficients in the shading program. TWH

Noticed oil drilling rig set up ~3/8mile south of site.  Didn't appear to be
more of an obstruction than the nearest pump-jack (a rather open structure).
I don't recall seeing this before (and Tom doesn't remember it from his visits)

Arrived 16:11

A series of tests were carried out to determine and reduce Kr signal noise 
The fast data was acquired for later analysis (logged as s7.020610):

- Battery pack ( 1.61v ) to AMP-9 - Good ~ 8035
- Battery pack to serial A/D - Good ~ 16065
- Kr 1394 installed (head in zip-log bag); wired directly to A/D (lots of 
  GOES noise)
17:00 disconnected the grey cable from Kr box and reconnected using 
      red cable (better shielding?)
17:05 removed plastic bag covering Kr head
- connected via front panel
Turned off station and re-did GOES shielding (twisted wires vs. clip leads to
  ground, shielded GOES transmitter power as well). Noise now ~80, 

A crudely-annotated plot of the above data is attached.

Conclusion: most of the "noise" seen on this station was still GOES 
interference.  I've significantly reduced it, but it is still present.

Time will tell if 1394 behaves better at this station than its former location
at s9.  It checks out okay in the lab (13mA, 1.7V in dry air -- even
better than 1392 that just came back from Campbell) and I've just replaced
the 4-pin connector which had a small amount of white corrosion.  Nevertheless,
I don't have much confidence that the connector change will fix the low-noise
problem.

Changed station configuration to use kry1394s.dat calibration file.

Set GOES transmission time by GPS. Was 4 sec off before correcting.

Dropped mast and mounted the three Kr heads below sonic. 

To test the kryptons, we first mounted each of the 3 krypton boxes (by 
climbing).  Then, we dropped the tower and mounted all 3 Kr heads near the 
sonic.  We raised the mast and took more data through various boxes.  Finally,
we dropped the mast to recover the 1393 & 1394 heads and raised the mast again.
Data were viewed locally using "fastsave" (after waiting 7-9 min :( )

The various combinations:
Head	Box	h2o	w'h2o'	h2o'h2o'
1391	1391	17.51	0.022	0.024
1391	1393	18.78	0.034	0.043
1391	1394	19.69	0.028	0.087
1393	1391	19.33	0.046	0.080
1394	1391	19.83	0.026	0.068
1394	1393	19.73	0.016	0.025
1393	1393	19.03	0.018	0.032
Done at 17:10

What I was expecting was near 0 w'h2o' using either 1393,1394 head or their
boxes.  These results don't make sense -- perhaps we got to this site too
late to have good fluxes.

To work with these data further, I swapped SDR 5 -> 2.

Final mast erection at 17:23

Departed at 17:30 

Arrived 14:12

Set GOES transmission time.

Exchanged serializer and examined noise:
Didn't have a working CSAT-1 serializer in the spare box :(, also the A/D
from the one CSAT-1 spare didn't work with the CSAT-1 CPU in the box.
Thus, changed to a configuration with the old CSAT-1 CPU and the A/D from
the UW-1 that we removed from s9 yesterday.  The reference voltages were
nearly the same -- the CPU is -88 and the A/D is -86.  I left it this way.
I used "fastsave" to examine the data, expecting a good result to be a large
reduction in h2o'h2o'.

h2o	w'h2o'	h2o'h2o'
17.82	0.029	0.145		before changes; obviously bad
17.91	0.023	0.199		"
18.24	0.023	0.028		change to -86 A/D; (short fastsave)
18.02	0.012	0.264		" (normal length fastsave)
18.03	-0.001	0.336		"; reseated all connectors on EVE and also 
				changed to spare Krypton signal cable

Obviously, none of these changes improved matters.  I went back to the normal
cabling, though I left the -86 A/D board in place.

The only thing I can think of next is to work on the front panel itself!

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.

- switched CR10 from 4th battery to 3rd battery, disconnected 3rd from 2nd,
  removed 4th battery (with controller/monitor)
- checked krypton signal -- was low, reseated connector -- was 30-13000mV,
  knew that this meant bad signal (coax) cable/connector problem, but that
  connector inside box checked out okay yesterday.  Deduced that the problem
  was the coax cable, played with cable, now 600mV.  THIS CABLE PROBABLY
  SHOULD BE REBUILT.  S/N 1390.

Peggy Lemone and Fei Chen visited yesterday.  I took them to sites 7,9,8 while
I rehung krypton electronics (which were cleaned up and had new 6-pin connectors
installed in the trailer) in plastic boxes and downloaded /card.  All of these
were serviced by climbing -- the towers were not dropped.

It was raining during all of these visits, so all kryptons were wet.  All 
krypton signals were only ~30mV -- hopefully they will recover.

I intended to do the logger power rewiring at s7 and s9, but forgot to bring
power cables :(

Approximate times were:
s7: 1340-1420 (drove in -- Peggy walked)
s9: 1530-1600 (started to drive in, got stuck in the mud!)

Departed at 14:50

We got to s4 about 1216.  I captured a lot of stuff onto file s4.020531.
During this time, we captured a GOES transmission with Tsfc, I think, then
turned the station off from about 1222-1229 while I put braid (ground strap)
around the krypton signal cable in the EVE box.  Upon restarting, the serializer
didn't come up, but did after I disconnected and reconnected the DB9 on it.
I then captured the KH2O during a transmission -- a jump was not apparent,
but the krypton signal was highly variable.

Turned GOES off at 1238.
Saw the King-Air go by E-W about 1/2mi north about 1300, turn around, and come
back a few minutes later.  Took several boring photos of it -- Tony thinks he
got a good one with our tower in the foreground.
Took a dirt clod sample at 1320 and left the site.

We just finished a site visit to s6.  (I'm writing this on aster on the road 
to s4!)  Since the King-Air is flying today 12:30-16:00 over the Central legs,
we decided to turn off all GOES transmitters from 4-6.  (s5's we apparently
forgot to turn on at the end of yesterday, so it is already off.)  
Our sequence was:
- 10:46 turned off GOES (SE120)
- a few minutes later decided to turn back on and log "jump"
- captured end of Tsfc jump -- not very apparent -- as "s6" (will rename later)
- had to reboot EVE and restart minicom since console locked up
- captured KH2O jump (not obvious, but large fluctuations) and next Tsfc jump
(160 counts = 16mV) as "s6.2"
- copied /card to Panasonic
- decided that krypton voltage was low (~150mV), so we cleaned by quickly 
dropping the mast, cleaning ~11:00, and reraising.  New value is ~320mV.
(We want good krypton data for today's flight.)
- 11:06 unplugged GOES again and headed off to s4.

Noted that TRH fan was okay and prop was spinning.

Arrived at 16:00.
There were oil-field workers doing things near the site.
The mast was not lowered.
The Kr was cleaned and signal improved from 150 mv to 460 mv
The TRH fan sounded OK as did the radstand multiplexer.
Following the procedure adapted at site 5 we removed the GOES DCP transmitter 
 and repositioned it outside and below the EVE box, with a tupperware cover.
Then we discovered that there still was GOES interference of 180 counts on Tsfc.
 (Unfortunately we had not tested for noise before making the change)
We also captured the data from /card.

Arrived at site 5 at ~ 13:30 and began a series of test on the GOES interference
At 13:50 began data capture, at 13:58:20 stopped data capture.  This to record
 the Tsfc and KH2O steps during a GOES transmission.  This file saved to 
 captures/s5.020530.
At 14:05 dropped mast and cleaned the Kr windows. 
 The signal increased (only) from 900 to 940 mV.  This  like a good
 level, but the dailyplots show bad data.  Hopefully, it is just a connector
 problem (though Gordon and Tom had looked at this before.)
At 14:15 demounted the Kr #1392 and replaced it with Kr # 1101. This Kr sensor
 had been brought into the base and had had the obvious corrosion inside the 
 electronics box removed and fresh silica gel in a cloth bag included. The 
 electronics box was also better sealed.
The signal changed Kr #1392 900mv to Kr # 1101 300 mv ( a decrease but hopefully
 a more stable sensor).
The TRH fan sounded fine, the Rad stand multiplexer sounded fine and the 
 propvane spun with no noise. The ports in the mast had already been duct taped  and so it was assumed that the Y cable had been inspected. 
The GOES tests result:
 noise even when Yagi deployed 10 m away 
 noise even with a dummy load
 reduction of noise on Tsfc from 250 counts to 15 counts when GOES transmitter 
 box outside the Eve box
As a result we rigged the cables out through a hole in the bottom of the box
 and placed the GOES box atop a battery box with a tupper ware cover.
We also captured the data from /card.

P.S. GOES data have stopped from this site.  We may have left the switch on the
transmitter off.  We'll have to run out again -- I don't think now, since it 
is late and Tony has left.  We'll plan on a run tomorrow -- they're planning on
flying this area anyway!

We also hit s8 today, after s7 (approx 1600-1840) and did lots of things:
- We discovered the ventilator fan on LW.out was dead. Checked it was fan and 
  not the power by swapping power with LW.in.
- We checked the gas cylinder pressures of Scott's CO2 system
    In order from the west (could not view all writing on cylinders):
       Site 8/4, 415.1 ppmv        2000 psi/8 psi
       Site 8/1,                    capped
       Site 8/3                    2150 psi/8 psi
       Nitrogen                     850 psi/4.5 psi
       Site 8/2, 355.8  ppmv       2000 psi/8 psi

- We lowered the mast about 1700-1830.  During this time, we:
	- cleaned the krypton
	- noted that the prop was stuck with dirty bearings.  We unscrewed the
	  prop end and sprayed with contact cleaner which got the shaft running
	  much better, though there still is a grinding noise
	- examined the Y junction in the S-bus cable and decided it was okay.
          We taped most of the holes with duct tape anyway.
- We disconnected power to the GOES transmitter and left it off.  (After 
  verifying that the A/D problem still was present, though only about 70 
  counts here.)
- We tightened all the CR10x screws -- some were loose.
- We tightened all the screws in the soil profile box -- many weren't tight.
  (after labeling the Echo probe wires, so we could put it back together)
- We disconnected 229 heating for a while to see if heating is causing the
  noise.  This was a bad test, I think, since the 229 output went offscale
  and became 9999.  (I don't understand why!)
- We connected all the 229 shields directly to power supply ground.
- We downloaded /card (twice!) (to examine the 229 data)
- We swapped the microdrive disk (replaced 2 with 5)

Tony found a tick crawling on the Eve box. Steve killed it.

Upon returning to the base, we did a "save_metppf" to get the data to Boulder.
This script died during the rsync to linus, so I repeated the last 2 steps
manually from ASTER.

P.S. The data seem to show no effect of the shield wire change or the screw
tightening efforts.

For next visit we need to take a radiometer ventilator fan and a propvane

We did several things at site 7.  Our primary reason for the visit was to see
if the glitch in the analog channels seen in the high-rate data at s8 also
occurred at non-supersites.  Using "sbusdebug" to watch Tsfc voltages, it was
obvious that the glitch does occur here.  The counts = 0.1mV changed by ~250
when the GOES transmitter was on.  I captured a bit of this on the Panasonic
using minicom (this file is now in $PAM/projects/IHOP02/captures/s7.020529).  
We further found out
by attaching the dummy RF load that this problem disappears.  Thus, it is an
RF interference problem.  We moved the antenna from the SW to E leg of the
tripod, but this didn't appear to work.  (Note that we left it in this position
which is rather close to the sonic.)  During the process, I rebooted a few
times and even powered-off the station once.  Note that the /card data should
recover much of the data while the GOES was off.

We left the station with GOES back running and the antenna near the sonic.

During all of this, an EVE error started appearing: "Illegal Address, 21 ticks".
Since all of the data channels appeared to be working, we ignored this.

Also, it seemed to me that the CR10x data didn't get started after one of the
reboots, so I used "lineon 2"; "lineoff 2" to get it going again.  I'm assuming
that this really wasn't necessary.

approximately 35 m WSW (221 degrees) of the site 3 PAM station (elevation
of CU station placement approximately 1m lower elevation than site 3
PAM station).

-The sonic anemometer and krypton hygrometer on the CU flux station
oriented to face true north per the instruction of Dr. Blanken. However,
since the dominant winds in the region are from the south, when the
tower is relocated to Site 10 these instruments will be oriented facing
east. The pyrometer and net radiometer are facing south and the IR
thermometer is monitoring surface temperature to the southeast of
the tower.

- The soil measurements associated with the CU flux station are taken
such that the CS615 probes collect soil moisture content at 5, 7.5, and
15cm; the pair of soil heat flux plates are placed on either side of the
CS615s at a distance of 10cm from center and at a depth of 5cm; the soil
temperature probe (not functional) is placed directly above the column
of CS615 at a depth 2.5cm. The entire collection of sensors is located to
the south west of the tower just outside the view of the net radiometer.

-CU flux station soil temperature sensor not functional due to missing
resistor.

Tried new 16 MB PCMCIA flash disk by rebooting EVE from stored
configuration.  This appeared to worked okay.

Measured Campbell multiplexer and logger supply voltages as 12.7 V.

Took site photographs.  First took two pictures of site from SE, then
two consecutive series of photos from next to the tripod at 45 degree 
azimuth intervals, starting from North and proceeding clockwise 
through E,S,W,N.

Clean optical sensors
---------------------
Clean PSP, PYG, Rnet, Rpar radiometers on dark horse
Check Rnet bubble level

If mast is lowered:
  Note times when mast is lowered and raised
  Clean kh2o
  Clean Everest
  Shoot prop and sonic azimuths with KVH data scope
    Declinations are west 7.5 deg, central 6 deg, east 5 deg
Else 
  Clean kh2o if within reach

EVE
---
Check and reset GOES clock with GPS
At sites 1 and 8 swap SDR microdrive (1 wk capacity)
Download (slow) local data storage; reboot EVE

KH2O
----
Clean internal power connector leads on stns 1:3,8

Soil profiles
-------------
Measure multiplexer and logger supply voltages at site 1:5,9

Test electric fence as applicable

If Joe and Josh are not taking soil moisture measurements,
then take a Trime reading near the ATD Qsoil and take a Trime 
reading and soil sample outside the radiometer footprints.

Tom visted site 8 5:15 - 7:05 pm CDT, May 19.

Replaced net radiometer, set GOES clock, downloaded (slow) local 
data storage. 

Measured multiplexer and CR10 supply voltages: 11.6 V

Tom visted site 7 2:45 - 4:45 pm CDT, May 19.

Cleaned the kh2o head and the power connector inside the electonics 
box, reset the GOES clock, and downloaded the local data storage.

Replaced EVE prom EVE 4/21/02 6047 with IHOP02 5/14 0xA7BA

Measured multiplexer and CR10 supply voltages: 14.0 V

Gordon and Tom visted site 6 13:50 - 19:10 CDT, May 18, including two
trips back to Wichita base.

We cleaned the kh2o head and the power connector inside the electonics 
box, checked the clock, and downloaded the local data storage.

We returned to the base, leaving the mast down, in order to repair
a broken connector inside the kh2o electronics and again to get a
cable needed to zero the NUW sonic.

See entry #97 about the attempted zeroing of the NUW#5 sonic, and
the eventual replacement with a K probe #980202.

Measured the power voltage at the campbell logger and multiplexer: 12.8 V.

The mast was down from 13:55 - 19:00 CDT.

Talked with Ken Andra at site.

Gordon and Tom visted site 5 11:00 - 12:00 CDT, May 18.

We cleaned the kh2o head and the power connector inside the electonics 
box, reset the clock (from 2 sec fast to 1 sec slow), and downloaded 
the local data storage.

Gordon sealed the Y in the Sbus cable with splicing tape and Peel
and Seal.  He also filed the inside of the TRH boom and remounted
the TRH inside the boom.

The mast was down from 11:10 - 11:50 CDT.

Gordon and Tom visted site 4 9:46 - 10:42 CDT, May 18.

We installed a new prom in EVE, cleaned the kh2o head and the
power connector inside the electonics box, and downloaded the
local data storage.

Visited site 8 on May 16, to fix barometer, get fast & slow data, 
and check GOES.

See entries 80,81,82

Arrived 17:30, CDT

Prop vane reporting constant wind direction, -99
Prop PO command reported jibberish.
TRH out.

Replaced TRH 104 with 704. 704 reported data.

Removing TRH was difficult, needs crossarm expansion fix

TRH704 is lashed under cross arm rather than inserted in end

TRH cable was dripping water.  Water in TRH connector.
Removed end cap of TRH housing, electronics were dry.
Somehow water is coming down within cable inside of
mast or is a result of condensation.  Shook water
drops from cable repeatedly, until, by end
of visit, cable was not dripping as much.

Tested #104 after blowing water out of connector.
#104 works, but left 704 in.

After these fixes, prop starting working - so it appears
the prop vane's problem was due to water in the sbus
cable.

Lowered mast to check for source of water entry, found
nothing obvious. Did not remove cable from mast. Raised mast.

From the sonic w and prop Spd data it appears the mast was lowered 
at about 18:10 CDT and raised at 18:55.

Note (7/17/02): Looks more like 1815 - 1850 CDT.  TWH

Shot angles with KVH data scope. See entries #75,76

Left site at 19:30

Arrived 12:50, CDT

Attached eve box ground strap

downloaded metppfs to panasonic

cleaned radiometers

cleaned krypton: 
	before: 657 mV, 10.35 gm/m^3
	after:  779 mV,  9.45

checked logger coefficients, two were wrong, see entry #73

took trime soil moisture readings, 

TWH note (7/18/02): Gordon forgot to enter the Trime measurements in
the logbook.  Here they are from his field notes:

   %vol   TDR
   3.9    57
   2.7    59
   4.4    55

took photos of site, including CU flux station
left 13:50

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)

Gordon and I visited site 9 from about 1830 - 2030 CDT to work on 
the kh2o.  I cleaned the radiometers and Gordon downloaded the local
data storage.

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.

arrived about 16:00 CDT   John and Gordon

First worked on CSAT/serializer, which has not been reporting. See entry #58

cleaned Rlw.in, Rsw.in, Rpar, Rnet with Kimwipe & distilled H2O
  domes looked quite clean beforehand

cleaned krypton with qtip & distilled H2O.
   Voltage before:  350mV, after: 670 mV

checked logger coefficients, all correct. See entry #59

installed ground strap on eve box

downloaded slow data

Power monitor system:  old version=IHOP_AD.ALT
  Vbatt OK at 13 V
  eve showing Icharge=249, Iload=.3
  Meter at end of cable:  Icharge=30-60 mV,  Iload=11-12mV
  Saw negative voltage on eve front panel. Looks like front
  panel has a problem  Trust Vbatt, not Icharge, possibly Iload OK

Trime: took 4 readings. See entry #60
