30M Krypton clean 1615 LT.

253: krypton, Site all, Thu 27-Apr-2006 18:50:37 PDT, Krypton cleanings - South, Central, West
The krypton hygrometers were cleaned as follows:

Central, 5m (Agee) - 1600-1607
Central, 30m - not cleaned due to high winds

South, 5m and 30 m (Poulos) - 1645-1705

West, 5m and 30 m (Poulos) - 1745-1800

The cleanings seem to have had a significant effect at the south and west tower kryptons(noted as sudden increases in kh2oV).

- 30m Krypton cleaned.  Voltage went from ~.9 to ~1.1 vdc

cleaned 5m krypton on short tower with methanol.
Voltage changed from ~.2 to ~.5, not spectacular.

Note: very windy and this short tower swaps a great deal.

137: krypton, Site west, Sun 02-Apr-2006 08:12:47 PDT, Krypton clean and s/n at West
The kryptons were cleaned at west at ~16:45 pm.

kh2o s/n at 5 m = 1395
kh2o s/n at 30 m = 1258
132: krypton, Site central, Sat 01-Apr-2006 13:48:14 PST, maintenance at central
Steve and Tom at central tower.  Steve climbed 30 m tower 11:40-12:20 PST to
investigate communication problem and clean kh2o at 30 m.  Then cleaned kh2o
and Licor 7500 at 5 m; off 5 m tower at 12:34 PST.

KH2O s/n = 1394 @ 30 m
           1390 @ 5 m

Finally, Steve cleaned 10 m radiometers with mop.
Also added yokes for steps and safety rope on 10 m radiometer tower.

102: krypton, Site west, Fri 24-Mar-2006 14:41:30 PST, Cleaned KH2O at west
Steve cleaned the KH2O at west; on tower from 1258 - 1318.

Cows in vicinity.  Need to activate the fence.

89: krypton, Site all, Wed 22-Mar-2006 10:05:43 PST, Cleaning KH2O windows
I called Campbell today and they recommended muriatic acid for cleaning KH2O

81: krypton, Site all, Mon 20-Mar-2006 10:21:24 PST, KH2O serializer data
FYI, the "serializers" don't digitize fast enough to keep up with 60Hz, 
so every fifth(?) sample from the kryptons is NA.  Since humidity fluxes 
are a low priority for TREX, and fluxes can still be calculated, I have 
not been worried about this .
