Summary: Oak leaves came out 2 weeks early, CO2 profile CO2 tank empty, Rotated CO2 soil probes, removed one, swapped 7500 at Vaira

When: Date: 3/18/2014 , Day: 77 , Watch Time: 9:30 am . Where: Tonzi/Vaira Ranch Who: Siyan Weather: clear, sunny, a perfect spring day Phenology: 100% of oak leaves came out at Tonzi, about 2 weeks earlier than multi-year average; no cows at both sites. Summary Swapped memory cards of CR1000s at three sites. Everything worked well. Checked and downloaded winflux and met data from PC at Tower, Floor, and Vaira. The CO2 profile system wasn’t calibrated on site due to empty CO2 tank. Checked the soil CO2 probes at Tonzi and Vaira; relocated probes at Vaira-west and Tonzi-Tree profiles to see whether rotation of probes would change difference in gradients of soil CO2. Read dendrometers Measured soil moisture Measured grass height Measure groundwater well Vaira_Grass Site Fence and gate power: 12 v. Downloaded Phenocam images. Swapped the memory cards of CR1000. Swapped Li-7500s. sn 0035 on, sn 0041 off. 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: CO2 tank, 404.02ppm, 0, 18psi N2, , 900, 10 Is the pump running‌ YES! No calibration performed at the site due to the empty CO2 tank. Will be replaced next week. 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!
