When: Date: 10/22/2009 , Day: 295 , Watch Time: 5:40am .
Where: Tonzi/Vaira Ranch
Who: Siyan
Weather:nice breeze
Phenology: tree litter fall 80%; grass germinated, but yellow litters still covered new grases.

Tonzi
Grass germinated	Oak leaf hasn’t fallen off totally.
Vaira:
Grass litter covers new grasses.

Summary

1. Pre-dawn leaf water potential: oak leaf= -16 bar; pin needle=-10 bar.
2. A-Ci curves for oak and gray pine
3. checked and downloaded data at Tower, Floor, and Vaira
4. calibrated Li-800 in the field because bump was dead.
5. collected samples of oak leaves and pin needles
6. dendrometers
7. soil moisture
8. groundwater well:

2. 
3. Check the fans of air temp. and relative humidity sensors at Vaira. YES!
4. Check MD-9 system connections YES!
5. Check CR23X with two multiplexers

1. Check levels of Radiation sensors, clear up surfaces.YES!
2. Check rain gage, make sure not clogged. YES!
3. Closed gate and set up fence. YES!

Tonzi_Tower Site

1. downloading data YES!

1. check the fans of air temp. and relative humidity sensors on the tower and the floor. YES!
2. Check rain gage, make sure not clogged. YES!
3. Check calibration cylinders;

CO₂ psig; flow psi; 418.8 ppm.
N₂ psig; flow psi.
Manually calibrate Li-800. Following Ted’s instruction: H:\IoneSavanna_2004\Tower_2004\CO2Profile\LI800_Calibration_Procedure_2Nov04.txt
Is the pump running‌ YES.

span

1. close gate and set up fence. YES!

Toniz_Floor Site

1. Fence and gate power: 12 v.
2. Panel and Batteries: 12.3 v; 1.5 amps; 1.9 amps. (about 7:00 am local time)
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!

1. Check MD-9 system connections YES!

CR23X3 – floor-Met








CR23X5 – soil CO₂ profile


CR23X6 – tower-Met







CR10X2 – floor-Met

1. Soil CO₂ profile: no power when I got there. I unplug and re-plug fuses, then the system back to work.
