Summary
  1. Did pre-dawn water potential measurements for oak leaves and pine needles
  2. Swapped memory cards of CR1000s at three sites. Everything worked well.
  3. Checked and downloaded phencam, winflux and met data from PC at Tower, Floor, and Vaira.
  4. The CO2 profile system was calibrated on site. Zero had big offset.
  5. Checked the soil CO2 probes at Tonzi and Vaira; install new probes at Tonzi open sites.
  6. Read dendrometers
  7. Measured soil moisture
  8. Measured grass height
  9. Measure groundwater well

  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:
