Summary

1. Nitrogen tank pressure is low: N₂ 650 psig;
2. measured pre-dawn leaf water potential (~10 bar)
3. swapped Li-7500 at Tower nd Vaira
4. checked and downloaded data at Tower, Floor, and Vaira. Three systems worked well.
5. Calibrated Li-800 in the field (bring the copy of Ted’s instruction).
6. samples of oak leaves
7. dendrometer
8. soil moisture
9. groundwater well

Vaira_Grass Site

1. Fence and gate power: 12 v.
2. Panel and Batteries: 12.0 v; 6.1 amps; 2.2 amps.
3. Reading from Gillsonic screen before downloading data. (The value of H₂O and CO₂ should be in the range of 0 – 5 v.)

after swap

1. downloading data

1. swaping Li-7500 Analyzer. (Remove SN# 418 ; install SN# 41 )
2. Swapped a new fan for air temp. and relative humidity sensor at Vaira.
3. Check CR23X: Sys_vot = 13.48

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: 13.2 v; 0.0 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!

1. swaping Li-7500 Analyzer. (Remove SN# 976 ; install SN# 42 )
2. check the fans of air temp. and relative humidity sensors on the tower and the floor.
3. Check rain gage, make sure not clogged. YES!
4. Check calibration cylinders;

CO₂ 850 psig; flow 20 psi; 431.25 ppm.
N₂ 650 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 running‌YES!

1. close gate and set up fence. YES! The voltage is less than 12v. Checked the fence around, didn’t see broken wire.

Toniz_Floor Site

1. Fence and gate power: 12 v.
2. Panel and Batteries: 12.3 v; 0.0 amps; 0.2 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
2. 

1. Check MD-9 system connections

CR23X3 – floor-Met

CR23X5 – soil CO₂ profile


CR23X6 – tower-Met


CR10X2 – floor-Met

1. Soil CO₂ profile
