When: Date: 9/19/2008 , Day: 263 , Watch Time: 10:30am .
Where: Tonzi/Vaira Ranch
Who: Siyan, Stefania
Weather: Dry, nice cool breeze
Phenology: oak leave 90% yellow at Tonzi, 30% at Vaira.
Talked with Mr. Tonzi. He recalled dry years: 1860-1861, 1975. Mr. Tonzi got out of cow business in 1975 because it was an extremely dry year.
Summary:

1. check and download data at Tower, Floor, and Vaira. Three EC systems worked well.
2. Calibrate Li-800 in the field. CO2 profile system worked well, but CO2 tank is 500 psig. Should we order a new one and replace it soon‌
3. read dendrometer
4. measured soil moisture

Vaira_Grass Site

1. Fence and gate power: 12 v.
2. Panel and Batteries: 13.8 v; 11.2 amps; 1.9 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 on the tower and the floor. YES!
3. Check rain gage, make sure not clogged.
4. Check calibration cylinders;

CO₂ 500 psig; flow 20 psi.
N₂ 1100 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!
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.
