Summary
  1. Swapped memory cards and download flux and met data and phenol-photos at three sites. Everything worked well.
  2. Checked and downloaded winflux and met data from PC at Tower, Floor, and Vaira.
  3. The CO2 profile system kept giving unreasonable readings after Joe cleaned it in the field. At last, Joe took it off and brought back to the lab.
  4. Read dendrometers
  5. Measured midday water potential
  6. Measured soil moisture
  7. Sampled litter biomass with 80x80 square.
  8. Measure groundwater well

Vaira_Grass Site
  1. Fence and gate power was broken. Joe fixed.
  2. Downloaded Phenocam images. (Joe)
  3. Swapped the memory cards of CR1000. (Joe)
  4. Checked the fans of air temp and relative humidity sensors at Vaira. YES!
  5. Downloaded met and soil CO2 profile data (joe)
  6. Checked levels of Radiation sensors, clear up surfaces.YES!
  7. Checked rain gage, make sure not clogged. YES!
  8. Closed gate and set up fence. YES!

Tonzi_Tower Site

  1. Fence and gate power: 12 v.
  2. downloaded Winflux data from PC. YES!

image008.jpg
  1. swapped the memory cards of CR1000.

image009.jpg
  1. download Phenocam images. Yes!
  2. checked the fans of air temp. and relative humidity sensors on the tower and the floor. YES!
  3. Checked rain gage, make sure not clogged. YES!
  4. Downloaded met data from PC. Yes.
  5. Checked CO2 profile:

IRGA gave unreasonable readings. Joe cleaned it in the field, but readings were still bad. At last, Joe took off the IRGA and brought it back to the lab.
