Tonzi: 2013-07-11 09:10:00 (DOY 192)
Author: Siyan Ma
Others: Joe

Summary: Standard fieldwork, midday water potential, CO2 profile pump down, HMP45 fan down at VR, Floor CR100 data not recorded - winflux okay

When: Date: 7/11/2013, Day: 192 , Watch Time: 9:10 am.
Where: Tonzi/Vaira Ranch
Who: Siyan, Joe
Weather: clear, sunny, nice breeze, getting drier
Phenology: yellow grasses; Joe noticed that some oak trees start to have yellow leaves; a few of small trees along the road in Tonzi Ranch to the tower; they are located on the area with lots of rocks.

Dead grass and green treesSome brown leaves on one of the oaks
Dead grass inside the biomass enclosureDead grass, blue sky and big tree at Vaira

Summary
  • Joe checked and downloaded data from PC at Tower, Floor, and Vaira.
  • Joe swapped memory cards of CR1000s at three sites and found the card didn’t work properly at Floor site. I learned the lessons again.
  • Fan of Hmp45 at Vaira was not working. It will be replaced next visiting.
  • Pump of the CO2 profile system was dead. It will be replaced next visiting.
  • Measured Midday water potential.
  • Read dendrometers
  • Measured soil moisture
  • Measure groundwater well:

Vaira_Grass Site
  1. Fence and gate power: 12 v.
  2. Panel and Batteries: - v; - amps; - amps.
  3. Swapped the memory cards of CR1000 (Joe).
  4. Check the fans of air temp and relative humidity sensors at Vaira. No!
  5. Check levels of Radiation sensors, clear up surfaces.YES!
  6. Check rain gage, make sure not clogged. YES!
  7. 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 from PC. (Joe)
  2. Swapped the memory cards of CR1000. (Joe)
  3. check the fans of air temp. and relative humidity sensors on the tower and the floor. (Joe)
  4. Check rain gage, make sure not clogged. YES!
  5. CO2 profile system: Is the pump running‌ No!
  6. 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.) (Joe)
  4. downloading data from PC. (Joe)
  • Swapped the memory cards of CR1000. Joe found the card didn’t work properly at Floor site. I learned the lessons again: be much more careful when swapping the card! (1) push the button on CR1000 first; wait for green LED light on; then push the card out; (2) after push a new card in, should see the red LED light blink fast. It means the datalogger is checking and formatting the card. It may take a while to finish this process. I should come back to see the red LED light blink in a slower motion. It means the card starts recording data. (3) Always good to double check the card status by connecting CR1000 from the PC.
  1. Check MD-9 system connections YES!
