Where: Tonzi/Vaira Ranch
Who: Siyan
Weather: clear, nice breezle
Phenology

• 70% grass at Vaira turned to yellow, and 30% grass remained green.
• Broad leaf herbs was blooming, yellow followers. Most of tall grass started to seed and die. Broad leaf herbs were green.

Summary

1. check and download data at Tower, Floor, and Vaira. All is well.
2. Spectrum measurement was taken. Take off the level on one side to level the other side.
3. collected grass sample for LAI and dry materials in Tower and Vaira, oak leaves and branches for LAI and N
4. measure soil moisture and dendrometer

Vaira_Grass Site

1. Fence and gate power: >12 v.
2. Panel and Batteries: 13.7 v; 12.0 amps; 2.2 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
2. check the fans of air temp. and relative humidity sensors at Vaira. Good.
3. Check CR23X with two multiplexers: BUSY WITH COM
4. Check levels of Radiation sensors, clear up surfaces.
5. Closed gate and set up fence.

Tonzi_Tower Site

1. Fence and gate power: 12 v.
2. Panel and Batteries: 14.1 v; 0.0 amps; 5.6 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 !!!! D120, be careful bad naming in flux data. Filenames need to be changed before processing.
2. check the fans of air temp. and relative humidity sensors on the tower and the floor. Good.
3. Check calibration cylinders;

CO₂ 2000 psig; flow 20 psi.
N₂ 2000 psig; flow 15 psi.
7. pump of CO2 profile system sounds OK.
8. close gate and set up fence.
Toniz_Floor Site

1. Fence and gate power: >12 v.
2. Panel and Batteries: 13.7 v; 8.8 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.)
