Author: Siyan Ma
Others: Joe, Gerardo JPL

Summary: Standard field work, 80% trees brown - super early, missed midday water potential due to tank issues

When: Date: 8/26/2020 , Day: 239 , Watch Time: 9:30 am .

Where: Tonzi/Vaira Ranch

Who: Siyan, Joe

Weather: clear, sunny, smoke from wildfire

Phenology: 80% of Oak leaves are brown; the earliest date of senescence since site established; almost all leaves of individual trees are torched; may check heat wave last week

Summary

See Joeâ€™s notes on equipment maintenance and data downloading
Read dendrometers
Measured soil moisture
Measure groundwater well

5. Joe put a new tank (pressed air) at Tonzi for leaf water potential; the connection head size not matched; reported to Joe for a double check
