Other sites visited today: Vaira

Tonzi: 2012-09-05 05:30:00 (DOY 249)
Author: Siyan Ma
Others: Joe

Summary: Predawn water potential - new tank, standard field work, swapped new CR1000 card at Vaira, removed two SHF plates for cal, co2 profile down for IRGA service.


When: Date: 9/5/2012 , Day: 249 , Watch Time: 5:30 am .
Where: Tonzi/Vaira Ranch
Who: Siyan, Joe
Weather: cloudy, a few of rain drops
Phenology: golden grassland, oak leaves turned into light brown and dropped.



Summary
  1. checked and downloaded data at Tower, Floor, and Vaira
  2. Joe swapped the data card on CR1000 datalogger.
  3. Predawn water potential: oak -40~-58 bar (Joe brought a new air tank to the field and brought the almost-empty nitrogen tank back. )
  4. IRGA Li-800 gave numbers were out of Datalogger’s range in the field. Joe took it back to the lab.
  5. Joe uninstalled one soil heat flux sensor at each site for calibration that will be done by Sebastian in Canada.
  6. Read dendrometers
  7. Measured soil moisture
  8. Measure groundwater well:

Vaira_Grass 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.)


Readings from CR1000
  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


  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.)

  1. downloading data YES!
  2. check the fans of air temp. and relative humidity sensors on the tower and the floor. YES!
  3. Check rain gage, make sure not clogged. YES!
  4. No calibration was performed for CO2 profile system because IRGA Li-800 gave numbers were out of Datalogger’s range in the field. Joe took it back to the lab.
  5. 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.)

  1. downloading data YES!
  2. Check MD-9 system connections YES!

CR23X3 – floor-Met
CR23X6 – tower-Met
CR10X2 – floor-Met
CR23X5 – soil CO2 profile




  1. Close gate and set up fence. YES!
