When: Date: 1/8/2010 , Day: 8 , Watch Time: 9:50 .
Where: Tonzi/Vaira Ranch
Who: Siyan Joe Naama
Weather: foggy on the way, cloudy, and rains in the afternoon
Phenology: yellow grass, green oak leaves

Tonzi

Summary

1. Show Naama the sites.
2. check and download data at Tower, Floor, and Vaira: Loading amps at Tower and Floor sites showed “low” when we got there. Power back after reset, but about one day data were lost. Joe found out that the long distance between the EC system and batteries may be the reason that cause the screen power problem at the floor site. He added an extra battery to the floor EC system, and the screen power problem was solved.
3. calibrate Li-800 in the field
4. dendrometers
5. soil moisture
6. groundwater well:

Vaira_Grass Site

1. Fence and gate power: 12 v.
2. Panel and Batteries: 12.1 v; 2.1 amps; 3.9 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
5. Check levels of Radiation sensors, clear up surfaces.YES!
6. Check rain gage, make sure not clogged. YES!
7. Closed gate and set up fence. YES!

Tonzi_Tower Site

1. Fence and gate power: >12 v.
2. Panel and Batteries: v; amps; amps. Loading amps showed “low” when we got there. Power back after reset, but about one day data were lost.
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 1200 psig; flow 20 psi; 418.8 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 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.)

(Didn’t do screen copy this time. )

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:

Joe replaced four old batteries with new ones.
See Joe’s notes.

1. Close gate and set up fence. YES!
