When: Date: 1/10/2006 , Day: 10 , Watch Time: 11:00am .
Where: Tonzi/Vaira Ranch
Who: Siyan
Weather: clear, breeze
Phenology: green grass

Summary

1. Tower’s Li-7500 readings were too low. Matthias and I reset power, but no use. Later on, Ted found there was bird crap on the sensor and fixed the problem.
2. Rain Gage was full of water. Need to be fixed.
3. CO2 profile: Maybe it is time to replace calibration cylinders!!
4. Vaira Met data were download to PC once in a while, not day by day.
5. Floor site, CD drive may cause the problem. Later on, talk to Ted. He said it is possible that running CD drove too much current. Sometimes the current is not good enough to do the job and then cause the restart failed.
6. Soil CO2 profile system
7. collected oak woody and grass samples in Tonzi (Alex)
8. measured soil moisture
9. read dendrometers

Vaira_Grass Site

1. Fence and gate power: >12 v.
2. Panel and Batteries: 13.7 v; 21.1 amps; 3.1 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. check the fans of air temp. and relative humidity sensors at Vaira. Good!
3. Check MD-9 system connections: “BUSY IN COM”, met data were download to PC once in a while, not day by day. Sys_vot and PC_start were not able to check from the keyboard.
4. Closed gate and set up fence.

2. Rain Gage was full of water. Need to be fixed.
3. downloading data
4. check the fans of air temp. and relative humidity sensors on the tower and the floor. Good!
5. Check calibration cylinders: Maybe it is time to replace tanks!!

CO₂ <100 psig; flow normal psi.
N₂ 500 psig; flow normal psi.
Is the pump running‌ Yes.

1. close gate and set up fence.

1. downloading data
2. Screen wasn’t connected with PC when I got there. PC seemed to be on at the time. CD drive may cause the problem. Later on, talk to Ted. He said it is possible that running CD drove too much current. Sometimes the current is not good enough to do the job and then cause the restart failed.
3. Soil CO₂ profile
