Summary: Standard fieldwork and data collection, Ameriflux inter-comparison running, midday water potential

When: Date: 4/20/2016 , Day: 111 , Watch Time: 10:30 am . Where: Tonzi/Vaira Ranch Who: Siyan Weather: clear, sunny Phenology: AmeriFlux comparison was running on site; a beautiful spring day; soil moisture still good; grassland looked patchy at Vaira; the density of oak leaves looked lower this year probably because severe previous droughts reduced establishment of leaf buds (see the picture below: no leaves on some twigs where leaves should grow supposedly) Summary Swapped memory cards of CR1000s at three sites. Everything worked well. Checked and downloaded phenocam images and met data from PC at Floor and Vaira. Checked the soil CO2 probes at Tonzi and Vaira; Read dendrometers Measured soil moisture Measured grass height Measure groundwater well Measure midday water potential of oak leaves Collect grass samples for LAI 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. 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! 6. closed gate and set up fence. YES! Toniz_Floor Site Fence and gate power: 12 v. 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!
