Summary: Standard fieldwork, CO2 profile system not working, error message on Floor computer.


When: Date: 9/29/2011 , Day: 272 , Watch Time: 10:00 am .
Where: Tonzi/Vaira Ranch
Who: Siyan
Weather: clear
Phenology: yellow grass, green oak leaves, dry, dusty

Tonzi

Dead grass and gree trees
A few flowers left in dead grass

Vaira:

Hill with dead grass and green trees
Dead grasses at Vaira field site

Summary
  1. checked and downloaded data at Tower, Floor, and Vaira
  2. Swapped Li-7500 at TZ Tower and Vaira.
  3. Calibrated Li-800 in the field.
  4. Collected samples of oak leaves and pin needles
  5. Read dendrometers
  6. Measured soil moisture
  7. midday water potential: seems lower than last time. Joe suggested that COSMOS data showed little moister recently.
  8. Measure groundwater well:

Vaira_Grass Site
  1. Fence and gate power: 12 v.
  2. Panel and Batteries: 13.2 v; 11.0 amps; 3.8 amps.
  3. Reading from Gillsonic screen before downloading data. (The value of H2O and CO2 should be in the range of 0 – 5 v.)

Vaira Gill sonic plots screen before downloading data
  1. downloading data
  2. swap Li-7500: install #42; remove #73.
  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. Fence and gate power: 12 v.
  2. Panel and Batteries: - v; - amps; - amps.
  3. Reading from Gillsonic screen before downloading data. (The value of H2O and CO2 should be in the range of 0 – 5 v.). Tower Gill sonic plots screen before downloading data
  4. downloading data YES!
  5. swap Li-7500: install #65; remove #1594.
  6. check the fans of air temp. and relative humidity sensors on the tower and the floor. YES!
  7. Check rain gage, make sure not clogged. YES!
  8. Check calibration cylinders;

CO2 1000 psig; flow 20 psi; 384.08 ppm.
N2 1500 psig; flow 30 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, but no good readings!

  1. close gate and set up fence. YES!

Toniz_Floor Site
  1. Fence and gate power: 12 v.
  2. Panel and Batteries: - v; - amps; - 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.)

First see “Error message on” the screen. Restart the computer and works well.
