When: Date: 1/19/2007 , Day: 19 , Watch Time: 9:30am .
Where: Tonzi/Vaira Ranch
Who: Siyan (met Ted at Tonzi)
Weather: partially cloudy
Phenology: grass didn’t grow very much at both sites. Grass at Tonzi looks yellow-green. This is a dry winter.
Summary

1. Ted saw “BLUE SCREEN DEATH” at Tower site. We lost raw data during Day 11-18.
2. swapped Li-7500 at Tower, Floor, and Vaira. Water and CO2 channels all worked well. The failure in calibrating water channel resulted from the dead descant.
3. PC clock at Tower is only 1 sec behind GPS. Correcting PC and dataloggers time at Floor.
4. Power on Floor site is OK.
5. Soil CO₂ profile worked well.
6. dendrometer, soil moisture, and spectrume were measured. Dendrometers need reset because some have been out of range!!!
7. Spectrometer data have sent to Youngryel for processing.

Vaira_Grass Site

1. Fence and gate power: >12 v.
2. Panel and Batteries: 13.2 v; 7.4 amps; 2.7 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 OK
2. swaping Li-7500: remove SN# 73 and install SN# 41.
3. Closed gate and set up fence.

Tonzi_Tower Site

1. Ted saw “BLUE SCREEN DEATH” at Tower site. We lost raw data during Day 11-18.
2. Ted will take away Li-cor PAR sensors and connect KZ PAR UP and DN to normal PAR channels. Change is needed in flux.cpp.
3. Fence and gate power: >12 v.
4. Panel and Batteries: 13.7 v; 0.0 amps; 4.8 amps.
5. 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 OK
2. swaping Li-7500: remove SN# 976 and install SN# 65.
3. PC time was about one second difference from GPS. No correction was taken.
4. check the fans of air temp. and relative humidity sensors on the tower and the floor.
5. Check calibration cylinders;

CO₂ 1400 psig; flow 18 psi.
N₂ 1300 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 OK

1. close gate and set up fence. OK

Toniz_Floor Site

1. Fence and gate power: 12 v.
2. Panel and Batteries: 13.8 v; 15.7 amps; 2.0 amps.
3. Reading from Gillsonic screen before downloading data. (The value of H₂O and CO₂ should be in the range of 0 – 5 v.)
