Vaira:

Summary

1. check and download data at Tower, Floor, and Vaira
2. Joe swapped a new pump for the CO2 profile system and calibrated Li-800 in the field.
3. Joe installed three new soil moisture probes at Vaira, but one of them was taken back because the forth channel always showed 41.4.
4. collected grass samples for LAI.
5. dendrometers
6. soil moisture
7. groundwater well:

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 at Vaira. YES!
3. Check MD-9 system connections YES!
4. 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: 14.0 v; 0.0 amps; 3.6 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 1750 psig; flow 20 psi; 384.08 ppm.
N₂ 1000 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 Joe installed a new pump and calibrated Li-800 in the field.

1. close gate and set up fence. YES!

Toniz_Floor Site

1. Fence and gate power: 12 v.
2. Panel and Batteries: 13.3 v; 15.4 amps; 2.0 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!

CR10X2 – floor-Met
CR23X3 – floor-Met
CR23X5 – soil CO₂ profile
CR23X6 – tower-Met

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