Summary: Standard field work, grass height, midday water potential, Tower computer having problems

When: Date: 4 /6/2015 , Day: 96 , Watch Time: 10:30 am . Where: Tonzi/Vaira Ranch Who: Siyan Weather: partially cloudy, cold Phenology: grasses in the reproduction stage; very different between in- and outside fence; dew on grasses surface; oak leaves are in dark green. The small pond at Vaira is still full. Summary Swapped memory cards of CR1000s at three sites. Everything worked well. Checked and downloaded winflux from PC at Tower and Floor. No signals on the screen of Tower PC when I got there; it worked after I restarted the computer. But after a while, no signals again. Later, “Beep” sound aroused from the box. Downloaded met data from PC at Tower, Floor, and Vaira. calibrated the CO2 profile system Checked the soil CO2 probes at Tonzi and Vaira; Read dendrometers Measured soil moisture Measured grass height Measure groundwater well Vaira_Grass Site Downloaded Phenocam images. Swapped the memory cards of CR1000. Checked the fans of air temp and relative humidity sensors at Vaira. YES! Downloaded met and soil CO2 profile data: 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 and gate power: 12 v. downloaded Winflux data from PC. YES! swapped the memory cards of CR1000. 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! Downloaded met data from PC Checked CO2 profile: Is the pump running? YES! 9. closed gate and set up fence. YES! Toniz_Floor Site Fence and gate power: 12 v. downloaded Winflux data from PC. YES! Swapped the memory cards of CR1000. downloaded met data from PC. YES! CR23X3 – floor-Met CR23X6 – tower-Met CR10X2 – floor-Met Soil CO2 profile: CR23X5 – soil CO2 profile Closed gate and set up fence. YES!
