When: Date: 2/10/2014 , Day: 10 , Watch Time: 9:00 am .
Where: Tonzi/Vaira Ranch
Who: Siyan, Joe
Weather: light rain in the morning, cloudy
Phenology: getting wet; Mr. Tonziâ€™s pond had some water; cows around at Tonzi

Summary

Joe checked and downloaded data from PC at Tower, Floor, and Vaira.
Joe swapped memory cards of CR1000s at three sites. Everything worked well.
Joe calibrated CO2 profile system; Zero and span seemed not stable.
Read dendrometers
Measured soil moisture
Measure groundwater well:
