Summary

Joe and Daphne took down the old set of IRGA and Sonic at each site
Joe swapped memory cards of CR1000s at three sites.
Joe checked and downloaded phenocam images and met data from PC at Floor and Vaira.
Read dendrometers
Measured soil moisture
Measure groundwater well and download GlobalWater data
Measure midday water potential of oak leaves
Collect grass samples for LAI
Spectrum of Vaira grassland
Download IRT data
