Tonzi: 2017-07-27 21:28:00 (DOY 208)
Author: Siyan Ma
Others: Daphne

Summary: Standard data collection, Collected pond data, midday water potential

When: Date: 7/27/2017 , Watch Time: 8:40 am .

Where: Tonzi/Vaira Ranch

Who: Siyan, Daphne

Weather: clear, sunny

Phenology: Water levels of Vaira ponds dropped. More leaves grew directly from the main trunk or larger branches, while smaller branches look dead.

Summary

Daphne downloaded flux data at three sites.
Daphne checked and downloaded phenocam images and met data from data loggers at Tonzi.
Daphne downloaded Vaira pond data.
Read dendrometers
Measured soil moisture
Measure groundwater well and download GlobalWater data
Measure midday water potential of oak leaves
Spectrum of Vaira grassland
Download IRT data
