Summary

Joe and Daphne set up new sets of IRGA and Sonic at three towers.
Joe swapped memory cards of CR1000s at three sites. Everything worked well.
Checked and downloaded phenocam images at Vaira
Joe let flux CR1000 collect phenocam images (up to 20 days)
Read dendrometers
Measured soil moisture
Measured grass height
Measure groundwater well and download GlobalWater data
Measure midday water potential of oak leaves
Spectrum of Vaira grassland
Download IRT data

Swapped the memory cards of CR1000. (Joe)
Joe and Daphne set up new sets of IRGA and Sonic
Checked the fans of air temp and relative humidity sensors at Vaira. YES!
Downloaded met and soil CO2 profile data (have been sent back to Berkele).
Checked levels of Radiation sensors, clear up surfaces. YES!
Checked rain gage, make sure not clogged. YES!
Closed gate and set up fence. YES!

Tonzi_Tower Site

Fence worked.
Joe set up new sets of IRGA and Sonic
swapped the memory cards of CR1000. (Joe)
download Phenocam images. Yes!
checked the fans of air temp. and relative humidity sensors on the tower and the floor. YES!
Checked rain gage, make sure not clogged. YES!
Screens of met dataloggers: (because the PC was crashed, data were downloaded at each data logger; Joe still worked on the problems of the data logger for tower met data.
