CuPIDO: Site 10 Messages, 46 Entries..

I went to site 10 to beep out the cabling for the Eppley PYG to the CR10X.
We need to make more cables for METCRAX. I had to disconnect the pyg
instruments for a short period. This event took place around 11:00 to
11:30 local time.

A.J.I. and Steve S. arrived 20:15 and left at ~20:45

Activities:
- went to investigate hightened Tsfc compared Tsfc.pyrg, determined that the 
sensor was facing a huge dead spot of sand while the rest of area is pretty 
well vegetated. So its seems ok.
- Downloaded program from datalogger which shut operations of logger from 13:21-
13:40
- Re-routed electric fence wire just to the top wire, it appears as though the 
bottom wire was shorted due to vegetation growth.

Gave a tour of site 10 to Constance Brown (Indiana Univ.), Karyn Sawyer, and
Jose Meitin yseterday.  Grabbed the USB data as long as I was there, but no
other service.   Everything seemed okay.  On site about 11:00-11:40.

0920 MST, 8/12

Trime: 6.7 (stomped a little), 7.8,7.7,7.6% (stomped more)

 Visited site, giving a tour for Susanne Grossman-Clarke of ASU.

While lifting charge controller out of battery box to inspect,
the load circuit connector was bent up, almost breaking its
connections to the board.  Shut down power and pushed connector
back down on the board.  Station is operating, but this
controller board should be replaced and inspected.

krypton cleaned at about 0030Z.  Mast down 0024-0034.  Voltage increased from
0.07 to 0.19V.  (I think this is a record for this sensor??)

Radiometers cleaned 0011-0014Z.  There was light dust on pyg.in.

1750 MST, 8/5

Trime:
moisure  11.2 (all 3 readings)

Took soil sample, tub#2 0-3 cm, tub#2 3-6 cm,
and rubbermaid tub labeled "stn2" was used for 6-8cm.


0-3 cm net weight in tupperware = 147.0 g - 46.1 g = 100.9 g
       net weight in Al foil tray =                  100.9 g
       net dry weight in Al foil tray =               94.3 g

3-6 cm net weight in tupperware = 159.8 g - 46.0 g = 113.8 g
       net weight in Al foil tray =                  113.6 g
       net dry weight in Al foil tray =              106.3 g

6-8 cm net weight in tupperware = 120.6 g - 43.1 g = 77.5 g
       net weight in Al foil tray =                  77.4 g
       net dry weight in Al foil tray =              72.4 g

Did 2 test tips at 0017 Z.

I just came back from a solo visit to 10 from ~1700-1750 (there was time both
before and after hauling stuff up and down the hill).

Actions:
- check fence -- seemed fine
- take photos
- swap USB
- upgrade software
- check "ntpq -p" -- gave -52 offset, 84 jitter for *GPS
- clean radiometers
- test rain gauge
- klean krypton (mast down 1725, up 1734)
- take TRIME and gravimetric sample
- tighten CR10 screws

Trime reading at 1457 MST:

21.7% moisture	28.0
22.9% moisture	29.0
23.1% moisture	29.0
23.2% moisture	28.0
22.8% moisture	28.0
23.0% moisture	28.0
23.0% moisture	28.0

23.3% moisture	28.0
23.2% moisture	28.0
23.3% moisture	28.0
23.1% moisture	28.0

Gravimetric sample had voids in soil (4 tries), so samples not good
for bulk density.  On second thought, I may have been resampling a
previously disturbed area, so take data with caution.

0-3 cm net weight in tupperware = 86.0 g - 46.2 g = 39.8 g
       net weight in Al foil tray                 = 39.3 g

3-6 cm net weight in tupperware = 164.8 g - 46.5 g = 118.3 g
       net weight in Al foil tray                  = 118.2 g

Found rain gauge tube clogged; plastic funned filled and dripping into
gauge.  Removed plastic tab, cleaned tube and re-assembled.

Tripped rain gauge at 1455 MST

Swapped USB disk.  Checked data from logger, TRH, prop-vane, barometer.

Arrived site 10, 1420 MST, July 29

Upper fence wire off SE stake, repaired; fence tested okay
Swapped USB disk, cleaned rain gauge tube, took soil samples, cleaned
radiometers

Departed 1540

Arrived 15:08 MST

Krypton voltage at 615 mV. Decided a cleaning wasn't necessary.

Radiometers clean and net radiometer level.

Swapped usbdisk.

Taped lid of GOES cooler.

Inspected and tipped rain gauge.

Sampled soil, see next entry.

Left  15:55 MST

Radiometers looked clean at site 10.

Leveled net radiometer.

Assuming net rad boom was pointing south,
bubble was NE of center, so radiometer
was pointing slightly SW.

Trime was not charged, so no trime sample.

Took 0-3 cm sample, in tub "#2, 0-3".  Other samples
failed, soil too loose. 

Tupperware lid came loose, so moisture not valid

net "wet" soil = Sample - tupperware = 123.9 - 46.1 = 	77.8 gm
net "wet" soil in foil tray = 				77.9 gm
net dry soil = 						77.3 gm

Lower mast at 11:03 MST

Cleaned krypton with distilled water and Qtip:

Krypton voltage:

before cleaning: 130 mV
after  cleaning:  95 mV
slowly rose to   100 mV


Voltage dropped after cleaning.

Raised mast: 11:22 MST  

Arrived 10:50 MST

Cover was off the electric fencer. Weighted it with rock. Cows nearby.

Taped lid on GOES cooler.

11:15 lowered mast, cleaned krypton (see next entry), raised mast at
11:23 MST.

Radiometers looked clean.  Re-leveled Rnet.

Swapped USB disk.

Attempted to take soil sample - soil very loose, only succeeded
in 0-3cm sample, in tub #2.

Trime unit was discharged.  Have to some back.

Left 12:30 MST

17jul06 12:40 - 14:50

Purpose: routine maintenance, logger power

Radiometers Cleaned 14:30

Logger Power re-arranged.
	Had to rewire to allow the logger to be powered directly from the
	main data system since we turned off the XBEE radios a couple days
	ago and disconnected the pv as a result.
	This box needs to be rewired anyway.

	Retrieved XBEE radios
	Removed 20w pv from top of sawhorse; which slightly improved the
	shading issue of the ground produced by the sawhorse/logger.

17jul06 12:40 - 14:50

Purpose: routine maintenance, logger power

Mast Down: 12:52-13:50

Krypton Cleaned: s/n 1101
	This *^(^ thing fooled me.
	I ended up cleaning it 4 times over and hour period
	because when doing data dump prior
	to cleaning it i thought i'd seen 200mV.  Then after the first
	and subsequent cleanings it went to between 100-130mV which made
	me think it got worse and been messed up.
	Wrong, Greg later informed me the pre-clean values had been ~20mV.

	According to Greg's analysis this unit is performing well across
	the spectrum to at up to ~14hz, however we may want to swap it
	out with the kh2o at 5 where the licor is colocated.

17jul06 12:40 - 14:50

Purpose: routine maintenance, logger power

Mast Down: 12:52-13:50

USB local data storage swapped/recovered

GOES pvc elbows installed and raised off ground to help ventillation

17jul06 12:20 - 14:50

Grabbed tub of soil.  This completes the tub soiling for Cupido.  Now Dr.O
will have plenty of dirt to play with back in Boulder!

ie radiometers all originally as planned and soils had been swapped from st5.
confirmed coefficients in logger per what SteveS sent

The radiation stand was raised between 1105 and 1150 LT.

The purpose of this was to eliminate some potential impacts of radiation from
bushes above the height of the LW.in sensor.

Initial impressions are that this had little effect. The hillside/valley location to the west may be the culprit, as may be a scratch on the sensor dome.

Greg

time: 1105-1239pm

TRIME measurement 9.7%
Gravimetric measurements for 0-3cm and 3-6cm (it took 20 tries and 3 insertions
to get the two samples because of rocks and soil falling out of the core. 


Gravimetric results (g):

Site 10 LW.in has seemed elevated relative to the other stations (~20 W/m2 most
of the day). There appears to be two main possible reasons.
1. The 4-component radiation stand is within 3 m of some vegetation (bushes) 
that project somewhat into the hemisphere.
2. There is a 1 cm long and < 1mm wide scratch on the dome. 

Tomorrow morning we will test #1 by elevating the radiation sensor another
 meter (max height) and observing the resulting changes in the radiation
measurements.

Pictures were taken of its current configuration and of the scratch.

Measurements can be considered disturbed (radiation primarily) 0938-1030LT.

There was a false rain spike during the visit.

HFT,jm: added direct cabling bypassing the Xbee Radios.....next morning no more
	glitches in the data plots.
	Thus confirmation that the XBEE radios are vulnerable to the dropped
	characters as we knew and expected.   Find reason later.....

13Jul06 9:30-10:30

Purpose: Swap logger to direct cabling to see if that will eliminate
the HFT glitches produced by character loss in the data
message.....done.

Note: This 'rf logger box' is wired such that the +v input can only go
through the solar charger.  This means it must run off the internal
battery and that battery must now be charged through the viper front
panel...this could be an issue for 'blowing it's fuse' and it'll be
interesting to find out.


Goes: box elevated slightly off ground.  This box needs to be
redrilled for drain holes since it wasn't correct.

The spectra were created via data_dump, scan etc.. We find that the spectra look close to -5/3 to 15Hz at Site 10 and all the way to 30Hz at Site 3 (operating at 60Hz). As a result we believe the low V krypton data is OK at Site 10, subject to further analysis.

10Jul06 16:00-17:30

Purpose: HFT has been glitching at night despite swapping in a replacement
	yesterday.

Examination of data revealed that the data messages from the logger are
being messed up by having characters dropped around the hft values.
This results in erroneous data being calculated in the averages.
Speculation that the maxstream radios may be 'burping' at night in
different radio propagation conditions, or lower batt voltage...hmmm.

1) Xbee radios here.  Cabling looks good.  But there are significant
bushes between the radio and receiver on the mast, plus that radio is in
the middle of the tripod with some 'shading' or reflective surfaces
from the tubing of the tower.

2) Boosted transmit power level from 'medium' (2), to 'highest' (4)
for the 2.4 radios

9Jul06 11:45-12:15

Purpose: HFT has been glitching at night
	New sensors received from Boulder last night.

	Disconnected, but left installed in soil: H983213
	Installed H983211

	Verified via rserial data consistency.

The data USB drive was exchanged at NNW (10) this morning at approximately 1130am LT.

7Jul06 12:05-12:40

Purpose: Cleaned radiometer domes with distilled h2o.  There were some
dirt splatters on the downward looking domes.  We did this because of
unusual discrepancies between the long-wave radiometer calculated surface temp. and the directly measured Tsfc values.   We had observed positive effects of cleaning the 'splattered' rnet dome at st7,st8.

This discrepancy began with the big rain event on the 6th, 0Z.  That
event left roughly 2' of silt in the wash near st8 and may have
included hail.  It's possible water got into the sensor/cabling,
thermister damage, dirt on the domes, etc.

We're continuing to investigating this issue.

7Jul06 12:05-12:40

Purpose: installed new software
see next log entry

The long, short and net radiation sensors at Site 10 have begun to deviate from their behavior previously. Specifically, the value of LW radiation (in, out) is large and the range of Tsfc is muted. Less noticeable, SW radiation is reduced. We have noted that during heavy monsoon rains that dirt can splatter the domes, preferentially the lower dome.

4jul06 14:00

Examined hft, nothing unusual in wiring that i can tell although resistor inside cable could be issue.  Symptom is glitching at night when the flux goes positive....Still happening.
May need to replace the hft.

4jul06 14:00

Mast Down 14:30 - 16:00

Tried to find cause of low kh20 voltages but really didn't.  Actual voltage going into serializer was 40mV....yuk.   Need to return with a different krypton and a better way to test the voltage output.  Power to the krypton was good.
Cleaned krypton and got some improvement.

Path length appears roughly 10mm....perhaps too wide given the moist for Arizona conditions?

The most recent version of cupido.xml was copied to the Viper at Site 10. The new C++ GOES code will be inserted during the next visit.

This krypton is reading very low voltages (under 0.1 V). Thus it was cleaned and voltage values were not improved. This sensor may be fading.

A six-point average of TRIME soil moisture at Site indicated 8.7%. The station is reading about 12% from the echo probe, which is about 4-5 times higher than the other three flux sites. Thus, this measurement corroborates a relatively high value. No other TRIME measurements have been taken.

Weepholes were drilled today (corners of bottom plate).

RM Young boom angle: 300 degrees
Sonic boom angle = 208 degrees
