When: Date: 9/25/2005 , Day: 268 , Watch Time: 13:00 .
Where: Tonzi/Vaira Ranch
Who: Siyan
Weather: clear with some white cloud
Phenology: dead grass, yellow spots on oak leafs. Trees around the tower showed yellow leaves. Cows are around at Vaira Site.
Summary

1. check Flux systems, download data: floor & tower met data from Day 220-now.
2. Soil CO2 profile system, tree spot #2 temp broken.
3. collect oak leaf samples in Tonzi
4. Alexander’s isotope samples
5. measure soil moisture
6. read dendrometer

Vaira_Grass Site

1. Fence and gate power: >12 v.
2. Panel and Batteries: 12.9 v; 5.4 amps; 3.0 amps.
3. Reading from Gillsonic screen before downloading data. (The value of H₂O and CO₂ should be in the range of 0 – 5 v.)
