Summary

checked and downloaded data at Tower, Floor
no PC at Vaira. Instead, one CR1000 collects flux 10 Hz data; one CR1000 collects photos; CR23X collects met data. Joe downloaded data from each datalogger.
Swapped Li-7500 at Tonzi Tower and Floor site.
Install 5 soil heat plates vertically at Vaira, combined with temperatures.
Gashound gas analyzer stopped working when we got there. Joe cleaned up and calibrated it in the field.
Read dendrometers
Measured soil moisture
Measure groundwater well:
