Tonzi: 2013-10-18 09:00:00 (DOY 291)
Author: Siyan Ma
Others: Joe

Summary: Standard fieldwork, Joe tested tipping buckets and leveled radiometers, Tram came in for repair, partial Moisture point due to dead battery.

When: Date: 10/18/2013 , Day: 291 , Watch Time: 9:00 am
Where: Tonzi/Vaira Ranch
Who: Siyan Joe
Weather: clear, sunny
Phenology: oak trees at Vaira still look green, while oak leaves are quite brown and fallen. The biomass fence was moved, and the TDR probes still in the fence. Mr. Tonziâ€™s pond has little water (see pictures below).

Summary

Checked and downloaded data from PC at Tower, Floor.
Joe downloaded data at Vaira and swapped memory cards of CR1000s at three sites. Everything worked well.
Joe leveled the radiation sensors and calibrated rain gauges at Tonzi and Vaira.
Calibrated CO2 profile system; Zero drifted -5 ppm.
The Tram cart wasnâ€™t functioning well and taken back to the lab.
Read dendrometers
Measured soil moisture (didnâ€™t finish because the battery was dead.)
Measure groundwater well:
