When: Date: 1/24/2006, Day: 24, Watch Time: 11:35
Where: Tonzi/Vaira Ranch
Who: Siyan
Weather: clear, hot sunshine, breeze
Phenology: green grass, still see brown grass litter. Looks like more tiny grass came out.
Summary

1. check and download data at Tower, Floor, and Vaira
2. swap Li7500 at Tower, Floor, and Vaira
3. something still wrong with the CR23X at Vaira, no Met data in the computer, “Busy with COM”.
4. Ted let me check the computer time and datalogger. They matched to each other pretty well.
5. At Tower, clean up bird crap on the solar radiation sensor. Since bird flu still makes threats, I recommend using gloves to deal with bird craps. Can we order some plastic laboratory gloves‌
6. soil CO2 profile: CO2 concentration at Channel 14 was -99999.
7. Measurements: soil moisture, dendrometer, spectrometer
8. samples: grass LAI, samples MIBA

Vaira_Grass Site

1. Fence and gate power: >12 v.
2. Panel and Batteries: 13.2 v; 6.8 amps; 2.6 amps.
3. Reading from Gillsonic screen before downloading data. (The value of H₂O and CO₂ should bein the range of 0 – 5 v.)

1. downloading data, but no Met data in the computer
2. swaping Li-7500 Analyzer. (Remove SN# 73 ; install SN# 42 ): readings were less than 1. double check the connections, and readings went back to normal, around 1.9.
3. check the fans of air temp. and relative humidity sensors at Vaira. Good.
4. Connection between computer and CR23X was successful once, and then “Error” occurred. Check computer time 01/24/06 12:26:44, datalogger time 01/24/06 12:26:32. So, 12 sec difference.
5. Check CR23X with two multiplexers, showing “Busy with Com”
6. Check levels of Radiation sensors, clear up surfaces.
7. Closed gate and set up fence.
8. spectrometer measurement taken
9. grass LAI sample taken
10. soil moisture measured

Tonzi_Tower Site

1. Fence and gate power: >12 v.
2. Panel and Batteries: 13.4 v; 0.0 amps; 3.5 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. Reading from Gillsonic screen after downloading data or swaping Li-7500 Analyzer. (Remove SN# 65 ; install SN# 418 )
2. check the fans of air temp. and relative humidity sensors on the tower and the floor. Good!
3. Check calibration cylinders;

CO₂ 2100 psig; flow 8 psi.
N₂ 250 psig; flow 10 psi.
May Nitrogen tank be almost empty‌
Is the pump running‌ Yes.

2. close gate and set up fence.
