When: Date: 3/27/2009 , Day: 86 , Watch Time: 10:00am .
Where: Tonzi/Vaira Ranch
Who: Siyan, Gretchen
Weather: clear, nice warm
Phenology: oak leaf out, vaira grass white flowers, Tonzi grass yellow flowers
Summary

1. WebCam wasn’t working. Talked to Joe on the phone. Replugged the power connections of tz6-23X datalogger. Problems were fixed.
2. Flux systems were working well at Tower, Floor, and Vaira, and data were downloaded.
3. Vaira 10Hz thermocouple looked very spiky.
4. Calibrated Li-800 in the field (bring the copy of Ted’s instruction).
5. Collected grass sample for LAI
6. read dendrometer
7. took soil moisture measurements
8. spectrometer (Youngryle)
9. filed pictures

Vaira_Grass Site

1. Fence and gate power: 12 v.
2. Panel and Batteries: 12.1 v; 5.9 amps; 2.3 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 on the tower and the floor. YES!
3. Check rain gage, make sure not clogged. YES!
4. Check calibration cylinders;

CO₂ 1750 psig; flow 20 psi.
N₂ 1250 psig; flow 20 psi.
Manually calibrate Li-800. YES! Following Ted’s instruction: H:\IoneSavanna_2004\Tower_2004\CO2Profile\LI800_Calibration_Procedure_2Nov04.txt
Is the pump running‌ YES! (an extra pump were put in the analyzer enclosure.)
How to check the CO2 values‌ Click “Ports/Flags” button to see which ports or flags is setting high. Pressure should be less than ambient value. When Flag 8 is high, it may indicate that RRR’s battery is low.
