IHOP02: Site 6 Messages, 31 Entries..

06/24/02  16:50 - 17:00 Local

The field was getting plowed while Steve was there.

06/24/02  16:50 - 17:00 Local

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

Trime measurements
ISFF	17.4
P1	18.4

  The mice came back home, All 4 of them! The aluminum foil
did not stop mom from crewing through. When I got there one little
guy was laying in the tipping bucket while the other 3 where
underneath the bucket.
  After eviction, I created a cardboard "plug" taped to the
bottom of the rain gauge. I have a feeling that mom will find
a way through it!

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.

06/20/02 18:35-19:15

Purpose: ati sonic still reading higher than RMY
	even after whacking Tom's weeds...but hey
	now we have a nice new weed-eater!

Swapped Sonic:
	Old= s/n 980202
	New= s/n 980504
	Preliminary results from examination at base
	indicates this fixed the problem.

Note About Kh2o placement:
	The new sonic has a level sensor.  We put it
	at the same respective position as on the old
	ati, which makes the kh2o tube very close to
	the level sensor box.  The open path is off to
	the side however, so this should be ok.

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.

The wheat at site 6 was harvested about 3 days ago. This
seems to correspond with the change in wind speed difference
between the sonic and the prop.

Below is additional information from Tom:

Tom spoke with Melva Andra today (June 20) by telephone to ask when the
wheat had been harvested at site 6.  She talked with Ken or Bryan by
radio and he replied that it had been harvested 2-3 days ago and seemed
to settle on 3 days ago, which would be Monday, June 17.  According to
our logbook, the last visit we made to the site was on June 12.  If
Joe/Josh/Heather visited site 6 on June 17-19, it would be valuable to
know whether or not the wheat had been harvested when they were there.

Reply from Joe:

Heather and I were at site 6 on June 19 and it had been harvested. When
I spoke to the landowner on the 14th, he said that due to the rain on
that day, they would have to wait 3 days to harvest the field. That
would place the harvest on the 17th which would correspond with the
date given to you.

As for site 5, it had not been cut when we where there yesterday (June
19) but they were working in the adjacent fields, so I would expect it
to be harvested today, or at the very least within the next few weeks.
This would also be in line with what the land owner told me last week.
At that time, he expected to harvest within the next week or ten days,
but could not be more specific.

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)


From Zeroing ATI inside van:

Station 6 prop may have bad bearings or the sonic is reading high.
A difference plot between the 10m prop and the sonic shows the
prop lower then the sonic. This change started taking place on the 17th.
  Comparing the two sensors to station 4 and 5, the sonic seems to
be reading high.

Arrived 16:00
Downloaded /card

Started raining on us ~17:50

Departed 18:00
 
Got the van stuck in the mud. Jon and Heather in the four wheel drive pick up
 also got stuck. Payed $40 for the farmer to pull us out with his tractor.

At several sites, especially s6 and also s5, there has been ongoing rain
indicated which we don't think can be real.  I've attached a plot showing
that for a 3-day period of clear skies over the entire state that accumulations
of up to 8mm of rain were indicated.  There doesn't appear to be a good
correlation with wind speed.  I would guess electronic noise is the source,
but haven't tried to isolate this.

Arrive: 1741
[ongoing check of radiometers]
- radiometers cleaned at 1750, dessicant okay 
- converted CR10 to fast mode; 0,1,0,0,0 coefs; collected data to s6l.020607
  (had to direct-connect to CR10, sites 4&5 I did through EVE "talk")
  at 1654; shaded 2x 1min each
- converted CR10 back to normal mode at 1758
Depart: 1802

Arrived  7:55, installed refurbished Kr 1397 on mast in plastic box
Connected CR10 to the independant third battery. PAM now has only two batteries
 on solar power.
Copied card, checked EVE output.
Departed 8:22

[another log of this visit later written by Tony]

Visit to reinstall krypton boxes after all that Tony brought back to the lab
yesterday passed inspection and to hang them in plasic boxes.  This to be
done before a King Air PBL mission today over the Central legs.

- arrive 0755
- installed plastic box and krypton electronics by climbing
- rewired CR10x power to stand-alone 3rd battery
- copied /card
- depart 0822

Kr electronic boxes collected from central sites.

Site 6, arrived 10:44, Kr 1397 box removed, cables bagged, departed 10:55

Note (7/26/02) This visit on June 5.  See entry 204.  TWH

Arrived at 13:05, departed at 13:55

Eve cables shielded from RF in "standard" fashion.
Standard fashion is:
        Ground strap over KH2O cable: front panel -> serializer
	Aluminum foil and duct tape over EVEAD cable: front panel -> EVEAD

Soil multiplexer screws tightened, Shields gathered to common ground.third hole

Attempted to obtained clods but soil too sandy to gather as clods

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.

Visited site 6, 1653-1723 CDT, May 27

Mast lowered 1700-1715 CDT

Cleaned KH2O
Opened KH2O electronics and looks okay.  Applied Seal & Peel to internal
connectors of KH2O

Gordon and I tightened the terminal screws on the Campbell data logger
and multiplexers, including that in the soil profile enclosure.

Gordon downloaded the data logger program, but had to use serial port
2 on EVE rather than port 6.  He could not talk to the logger through
port 6.

Gordon recycled Sbus power in order to restart the prop vane.  Its
direction was stuck at -99.  We did not recalibrate the prop.  Its 
coefficients were:

Gordon looked for water in the TRH plug, which had accompanied the 
same symptom at station 5.  He found the plug to be dry.

The ATI sonic was still programmed for 10 pulses per data output.  Changed
to 11 pulses per data output.

Visited station 6 from roughly 1445 - 1645 CDT, May 26

Restarted prop vane to cure direction error
Downloaded slow data
Tightened terminal screws in Campbell data logger and multiplexers
Changed sonic samples from 10 to 11 pulses per data output
Took 360 degree photos
Gordon downloaded Campbell logger program.

Arrival: 1200
Departure: early afternoon

-No maintenance or measurements performed, only visited site for survey
with David Yates to discuss surface characterization sampling method

Someone requested several days ago that a zero calibration should
be done on the sonic at site 6, which is NUW#5.

After returning to site 6, May 18th, and installing the fixed krypton we
tried to do the zero calibration.

Swapped in serial cable within EVE to bypass serializer.

Blue styrofoam zero-wind chamber on the transducer axis aligned
with U.

talked to UW, sonic, requested a calibration from menu, selected U axis.
Did not have an exact temp and RH, so we entered a guess for the
first time through.  Sonic answered that it was performing
the calibration, followed by series of dots  ........
It never returned to a prompt. After several minutes we powered
it down and back up.  On power up it would then only report:

  Bad factory checksum!
  Bad user checksum!

We returned to the base and brought back the "known state" cable for ATI
sonics.  We powered up the sonic several times with the known-state wire
shorted to the ground wire, but each time the sonic only reported
the same bad checksums. We also tried connecting known-state to ground
while it was powered up, still no response.  Did not try grounding
the reset pin.

So we then installed a K probe, 980202.  The krypton head is oriented
horizontally.

Mast back up at 19:00

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.

The wind direction at site 6 was stuck at ~ 260 degrees.  This was
fixed around 1830 GMT by recalibrating the prop vane direction encoder.

It appears from the sonic data that the mast was lowered 
from 18:15 - 18:30 GMT, May 11.

Checked logger coefficients at Site 6.  
They were as listed in logbook entry 19.

Site 6 was completed today.
Sonic serial number: NUW 5
Sonic Height: 4.9 m
Sonic Direction: 85 degrees
Krypton serial number: 1397
Tsfc serial number: 3389-1
TRH serial number: 701
Prop serial number: 00319
Prop direction: 176 degrees
Radiation height: 2.32 m
Profile box: 1

NOTES:
   The canopy was .6 m. The radiation stand was set to
its full height. The 2.32 m setting is from the ground to
the top of the K&Z sensor.
   The barometer is ok but this one has a bad 485 xcvr. The
232 interface is being used here.
   The output power of the GOES unit is low, 7.5 watts. A reverse
power of 0.3 watts.
   The original PCMCIA card bad. Took card from station 8.
   Morningstar charger was bad. Changed to a new unit.
