Summary: Standard fieldwork, things look very dry

When: Date: 09/04/2013 , Day: 247 , Watch Time: 10:50 am
Where: Tonzi/Vaira Ranch
Who: Siyan
Weather: clear, sunny, ~30^oC, nice breeze
Phenology: dead grasses; leaves of oak trees turned into brown, like being torched; a large area of grassland by the road was packed by vehicles at Vaira, probably because the owner family did horse riding over there.

Summary

Checked and downloaded data from PC at Tower, Floor.
Download phenocam images from the small PC at Vaira
Download Vaira Met and soil CO2 profile data from the field laptop.
Swapped memory cards of CR1000s at three sites. Everything worked well.
Calibrated CO2 profile system.
