Tonzi: 2012-05-30 09:30:00 (DOY 151)
Author: Siyan Ma
Others: Martin, Nhat

Summary: Grasses are senescent, tried swapping Floor IRGA but new IRGA had bad water, well batteries bad, could not collect Vaira soil CO2 data.


When: Date: 5/30/2012 , Day: 151 , Watch Time: 9:30 am .
Where: Tonzi/Vaira Ranch
Who: Siyan, Martin, Nhat
Weather: clear, sunny
Phenology: 90% of grasses were senescent at Vaira, 70% at Tonzil.

Summary
  1. checked and downloaded data at Tower, Floor, and Vaira
  2. Tried swapping Li-7500 (#35) at TZ Floor site, but the H2O channel of #35 didn’t work this time. #35 was taken back to the lab for check.
  3. Calibrated Li-800 in the field.
  4. Collected grass samples for biomass
  5. Measure midday leaf water potential: ~-10 bar for oak leaf; <-2 bar for pine needles
  6. Read dendrometers
  7. Measured soil moisture (with Martin and Nhant’s help)
  8. Didn’t get good reading for groundwater well. Probably the battery was dead.

Vaira_Grass Site
  1. Fence and gate power: was not on 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.)

  1. downloading data
  2. Check the fans of air temp. and relative humidity sensors at Vaira. YES!
  3. Check MD-9 system connections YES!
  4. Check CR23X with two multiplexers

However, still can not talk to the datalogger of soil CO2 profiles.

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

CO2 - psig; flow - psi; 421.63 ppm.
N2 - psig; flow - psi.
Is the pump running‌ YES!

  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.)

Floor Gill sonic plots screen before downloading data
  1. downloading data YES!
  2. Check MD-9 system connections YES!
