230: krypton, Site 10, Sat 05-Aug-2006 19:20:11 MST, krypton klean
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??)

219: krypton, Site 3, Fri 04-Aug-2006 18:29:08 MST, krypton kleaned
krypton kleaned by mast down at 12:15.  Voltage 0.08 -> 0.2 V.
Mast back up 12:20.


218: krypton, Site 5, Fri 04-Aug-2006 18:28:09 MST, krypton kleaned
krypton kleaned by Gordon climbing at 09:21.  Voltage 0.07 -> 0.12 V.

184: krypton, Site 3, Thu 27-Jul-2006 09:31:46 MST, Station visit, site 3: cleaned KH2O
Cleaned site 3 KH2O

Large tube on top
Took photo to show spatial displacement

Before cleaning 150 mV
After cleaning 115 -> 150 mv
164: krypton, Site 10, Mon 24-Jul-2006 22:55:03 MDT, Station 10 Krypton cleaning
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  

151: krypton, Site 5, Sat 22-Jul-2006 10:17:47 MDT, Station 5 – Krypton cleaned
Station 5 – Krypton cleaned

The krypton hygrometer was cleaned at 1245 with little change noted in the response.

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.

16Jul06 11:30 - 16:00

Krypton Cleaned: 12:00
	voltage raised from 350mV to 700mV

108: krypton, Site 2, Fri 14-Jul-2006 20:23:58 MDT, st2 Visit: Krypton cleaned
14Jul06 14:00 - 17:30

Purpose: Intermittent outages last night / routine maintenance

14:40 krypton cleaned, kh2o #1385 (must be 1395 and i couldn't read it correctly)
values went from .35 to .6vdc
96: krypton, Site 5, Thu 13-Jul-2006 16:33:26 MDT, St 5: Krypton cleaned
13Jul06 15:15-17:30

~17:00 The krypton hygrometer was cleaned.
	Voltage rose by 150mV which is about the same as it had deteriorated
	since the last cleaning cycle on the 2nd.

89: krypton, Site 10, Wed 12-Jul-2006 18:47:01 MDT, Low voltage krypton at Stn 10 versus Stn 3 spectra
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.

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?


21: krypton, Site 10, Sun 02-Jul-2006 22:17:44 MDT, Krypton cleaning Site 10 - very low voltage values
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.
8: krypton, Site 5, Sun 02-Jul-2006 20:24:17 MDT, st5 kh2o cleaned
2Jul06, 9:30-10:30 MST

Distilled water used to clean krypton.
Opened csat elec box to check voltages: .08 before, .25 after (but may have still been wet).

Note: decided against pivoting the xarm up because of 2 things: electronics box is mounted on top of the xarm right next to the tower and the cables to the rmy, irt are too tight.

Used 'stick-with-wick' method on the rohn tower.
