Tonzi: 2014-01-24 09:10:00 (DOY 24)
Author: Siyan Ma
Others:

Summary: Very dry, 50 cows at Tonzi, Tower fence broken - fixed, removed Vaisala CO2 probes for calibration, CO2 profile large offsets and data logger readings do not match licor interface, tram reinstalled, lost empty CF card near tower.

When: Date: 1/24/2014 , Day: 24 , Watch Time: 9:10 am .
Where: Tonzi/Vaira Ranch
Who: Siyan
Weather: clear, sunny
Phenology: Still so dry! Saw 50 cows at Tonzi. They looked mad and chased my car after I drove the crowd. Tower fence was broken; fixed.

Summary

Put Tram car back, and it parked to the charge station.
Took off soil CO2 probes at Tonzi and Vaira
Checked and downloaded data from PC at Tower, Floor, and Vaira.
Swapped memory cards of CR1000s at three sites. Dropped the memory card from the top of the tower and lost it. Downloaded data from the on-site card and put it back.
Calibrated CO2 profile system; Zero and span off 50 â€“ 80 ppm.
Read dendrometers
Measured soil moisture
Measure groundwater well:
