Author: Siyan Ma
Others: Jessica


When: Date: , Day: , Watch Time: .
Where: Tonzi/Vaira Ranch
Who: Siyan, Jessica
Weather: clear, nice breeze
Phenology: yellow grasses, see some yellow and big purple flowers
Summary
  1. Pre-dawn water potential measurement
  2. help Jessica do some leaf N measurements
  3. check and download data at Tower, Floor, and Vaira
  4. collect oak leaves and branches for LMA and N
  5. read dendrometer
  6. measure soil moisture

Vaira_Grass Site
  1. Fence and gate power: 12 v.
  2. Panel and Batteries: 13.0 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.)

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

CO2 1700 psig; flow 18 psi.
N2 1800 psig; flow 20 psi.
Manually calibrate Li-800. Following Ted’s instruction: H:\IoneSavanna_2004\Tower_2004\CO2Profile\LI800_Calibration_Procedure_2Nov04.txt
Is the pump running‌
How to check the CO2 values‌ Click “Ports/Flags” button to see which ports or flags is setting high. Pressure should be less than ambient value. When Flag 8 is high, it may indicate that RRR’s battery is low.
