Summary
  1. Checked flux and met data from PC at Tower, Floor, and Vaira, but no data were downloaded this time.
  2. Dennis put a new tank of CO2 for calibrating the CO2 profile system.
  3. Dennis cleaned up the sap flow sensors near the road well.
  4. Relocated probes at Tonzi-open profiles to Tonzi-Tree2.
  5. Read dendrometers.
  6. Measured grass height.
  7. Measured groundwater well.
  8. Collected grass samples for LAI at Tonzi and Vaira.

Vaira_Grass Site
  1. Checked the fans of air temp and relative humidity sensors at Vaira. YES!
  2. Checked soil CO2 profiles: all probes were dry.
  3. Checked levels of Radiation sensors, clear up surfaces.YES!
  4. Checked rain gage, make sure not clogged. YES!
  5. Cleaned the surface of Li-7500. YES!
  6. Closed gate and set up fence. YES!
