When: Date: 11/29/2009 , Day: 333 , Watch Time: 6:00 .
Where: Tonzi/Vaira Ranch
Who: Siyan
Weather: chilly in the morning
Phenology: yellow litters still covered green grassed, 99% oak leaf-off, some trees still had green leaves. Saw Mr. Tonzi. He mentioned two loads of cows (80) supposed to arrive in the afternoon, but they delayed because it was too cold in the mountain last night. He was not planning to cut more trees unless the trees fell on fences. His customers went away.

3. Reading from Gillsonic screen before downloading data. (The value of H₂O and CO₂ should be in the range of 0 – 5 v.)

1. downloading data YES!
2. swap Li-7500: remove #35, install #976 (with new chemicals)
3. Check the fans of air temp. and relative humidity sensors at Vaira. YES!
4. Check MD-9 system connections YES!
5. Check CR23X with two multiplexers

1. Check levels of Radiation sensors, clear up surfaces.YES!
2. Check rain gage, make sure not clogged. YES!
3. Closed gate and set up fence. YES!

Tonzi_Tower Site

1. Fence and gate power: 12 v.
2. Panel and Batteries: v; amps; amps.
3. Reading from Gillsonic screen before downloading data. (The value of H₂O and CO₂ should be in the range of 0 – 5 v.)

1. downloading data YES!
2. check the fans of air temp. and relative humidity sensors on the tower and the floor. YES!
3. Check rain gage, make sure not clogged. YES!
4. Check calibration cylinders;

CO₂ 1000 psig; flow 20 psi; 418.8 ppm.
N₂ 1400 psig; flow 20 psi.
Manually calibrate Li-800. Following Ted’s instruction: H:\IoneSavanna_2004\Tower_2004\CO2Profile\LI800_Calibration_Procedure_2Nov04.txt
Is the pump running‌ YES!

1. close gate and set up fence. YES!

Toniz_Floor Site

1. Fence and gate power: 12 v.
2. Panel and Batteries: 12.3 v; 1.5 amps; 1.9 amps. (about 7:00 am local time)
3. Reading from Gillsonic screen before downloading data. (The value of H₂O and CO₂ should be in the range of 0 – 5 v.)

1. downloading data YES!
2. Check MD-9 system connections YES!

CR23X3 – floor-Met


CR23X5 – soil CO₂ profile


CR23X6 – tower-Met


CR10X2 – floor-Met

1. Soil CO₂ profile: no power when I got there. I unplug and re-plug fuses, then the system back to work.
