When: Date: 11/4/2006 , Day: 308 , Watch Time: 9:00am .
Where: Tonzi/Vaira Ranch
Who: Siyan
Weather: clear, not too hot
Phenology: wet floor surface, no germination yet, tree leaves falling off, maybe 10% still on with some brown color dots. Met Mr. Tonzi.
Summary

1. EC systems worked well. Data were downloaded, including all missing download data before.
2. Li-7500 at Vaira and Floor were swapped. I was planning to swap IRGA (SN 0976) at the tower too, but CO2 channel kept giving me 0.0001. So, I swapped back to the old one, and I am going to swap it in two weeks.
3. performed spectrometer.
4. collected branch and leaf sample for N analysis.
5. MIBA samples were collected this time (No. 193-197).
6. measured dendrometer
7. measured soil moisture
8. Gave a tour to Andrew Oliphant’s students in Boundary Layer Class (Department of Geography, San Francisco State University, 1600 Holloway Avenue, San Francisco CA 94132, Ph: (415) 405-2143, Fax: (415) 338-6243)

Vaira_Grass Site

1. Fence and gate power: >12 v.
2. Panel and Batteries: 13.5 v; 16.5 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 (D212, D301-307)
2. swaping Li-7500 Analyzer. (Remove SN# 35 ; install SN# 93 )
3. check the fans of air temp. and relative humidity sensors at Vaira. Good.
4. Check MD-9 system connections: successful!
5. Check CR23X with two multiplexers

Sys_vot = BUSY WITH COM
PC_start = didn’t find it.

1. Check levels of Radiation sensors, clear up surfaces. Yes.

9. Closed gate and set up fence.
