Summary: Showing Hideki the site, Standard field work, check Floor batteries, wind profile removed

12/11/2008 (346) Tonzi

Joe and Hideki arrived about 12:00pm. Climbed tower to show Hideki and check on removing wind profile system. Hideki made soil moisture measurements. Joe made spectrum measurements and collected grass sample to the east of the tower.

Spectrum measurements done about 2:30pm in sunny patches to the east of the Tower. Integration time 275ms. Three rep in three locations.
Location height files
1 ~100cm (not recoded) tz_1_1 to tz_1_3
2 102cm tz_2_1 to tz_2_3
3 98cm tz_3_1 to tz_3_3

Phenology: maybe 5 to 10% leaves on trees mostly brown. Ground tinged with green, cm or two new grass dew in shady areas even at noon.

Tower:
Fence in yellow, system tested fine when not connected to fence. Walked fence and found to wire touching fence post in one location. Fixed â€“ full power when we left.
Batteries: 13.4V
Load: 4.6 Amps

Data checked and downloaded
Fan on to HMP45 not working
Rain gage clear little bit of water in tipping bucket
Radiation sensor dirty, especially pyranometer â€“ cleaned about 3pm
Bird protection on sonic kind of sideways â€“ lowered, straightened, raised about 3pm
Gas cylinders:
CO2 700 psig; flow 22 psi
N2 1800 psig; flow 22 psi
Did manual zero of CO2 profile system. Started to do span but didnâ€™t see how to tell the LI800 what the concentration of the span gas is so did not span. When flow the span gas (431.80ppm) the LI800 read 428ppm.

Hideki removed wind profile system. Mounting arms left in place. Power cable for 10x disconnected in power box and left on tower.

Gate closed and power up

Floor:
System was running, no problems with power even with screen and usb hard drive. I disconnected all the batteries and ran the system on a single spare battery while I let the batteries rest. After resting, all batteries tested good in voltage and under load. Reconnected all batteries and torqued connections with wrench.

Fence: +12V
Batteries: 12.9V
Panels: 19.6Amps
Load: 3.3Amps with screen and USB drive

Mr. Tonziâ€™s ATV is in the shop because it wonâ€™t go into reverse and a Forestry officer returned to him and sign from when he used to drive cows up into the mountains to graze. It is now mounted near his house â€œTonzi Cow Camp ->â€.
