Tonzi: 2016-04-20 10:30:00 (DOY 111)
Author: Siyan Ma
Others:

Summary: Standard fieldwork and data collection, Ameriflux inter-comparison running, midday water potential

When: Date: 4/20/2016 , Day: 111 , Watch Time: 10:30 am .

Where: Tonzi/Vaira Ranch

Who: Siyan

Weather: clear, sunny

Phenology: AmeriFlux comparison was running on site; a beautiful spring day; soil moisture still good; grassland looked patchy at Vaira; the density of oak leaves looked lower this year probably because severe previous droughts reduced establishment of leaf buds (see the picture below: no leaves on some twigs where leaves should grow supposedly)

Summary

  1. Swapped memory cards of CR1000s at three sites. Everything worked well.
  2. Checked and downloaded phenocam images and met data from PC at Floor and Vaira.
  3. Checked the soil CO2 probes at Tonzi and Vaira;
  4. Read dendrometers
  5. Measured soil moisture
  6. Measured grass height
  7. Measure groundwater well
  8. Measure midday water potential of oak leaves
  9. Collect grass samples for LAI
