Summary
  1. Measured pre-dawn water potential of oak leaves and pine needles: ~-30 bar for oak; ~-10 bar for pine.
  2. checked and downloaded data at Tower, Floor, and Vaira
  3. Swapped Li-7500 at TZ Tower, Floor, and Vaira.
  4. Turn off the CO2 profile system because the pump might not work properly. The pump was removed and brought back to the lab.
  5. Read dendrometers
  6. Measured soil moisture
  7. Measure groundwater wells
