Summary: Predawn water potential, reinstalled tram, Trouble connecting to data loggers at Vaira, no moisture point data, standard fieldwork.


When: Date: 5/8/2014 , Day: 128 , Watch Time: 5:50 am .
Where: Tonzi/Vaira Ranch
Who: Siyan
Weather: Cloudy in the early morning; sunny after 9:00am; Dew on the grasses
Phenology: Grass at filling stage, still green; a lot of wild oat, ~70 cm tall at least

Summary
  1. Put Tram cart back.
  2. Measured predawn water potential, still good!
  3. Checked and downloaded winflux and met data from PC at Tower and Floor.
  4. Connections to met and soil Co2 datalogger were not working at Vaira. So, data were downloaded directly from the datalogger.
  5. Served Z-cams.
  6. The CO2 profile system was calibrated on site.
  7. Read dendrometers
  8. Soil moisture wasn’t measure because no power when I turn it on. When I put the device on the charge in the lab, it seems full in power. I don’t know why.
  9. Measured grass height
  10. Collected grass samples
  11. Measure groundwater well

Vaira_Grass Site
  1. Fence and gate power: 12 v.
  2. Downloaded Phenocam images.
  3. Swapped the memory cards of CR1000.
  4. Checked the fans of air temp and relative humidity sensors at Vaira. YES!
  5. Downloaded met and soil CO2 profile data directly from each datalogger due to the connection at the PC station didn’t work properly.

  1. Checked levels of Radiation sensors, clear up surfaces.YES!
  2. Checked 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.
