Where: Tonzi/Vaira Ranch Who: Joe, Siyan Weather: clear, hot Phenology: yellow grass, green oak leaf, see acorns at Tree #92 Summary measured predawn water potential: oak=-32 bar; pine=-16 bar. checked and downloaded data at Tower, Floor, and Vaira took back Rain Gage at Vaira for checking (Joe) calibrated Li-800 in the field collected leaf and needle samples read dendrometers measured soil moisture took spectrometer measure at Vaira groundwater well Date DOY Location Depth (no the black thing) (feet) 9/2/2010 245 Floor 26.03 Tower 30.60 roadside 35.35 Vaira_Grass Site Fence and gate power: ok v. Panel and Batteries: ok v; ok amps; ok amps. Reading from Gillsonic screen before downloading data. (The value of H2O and CO2 should be in the range of 0 – 5 v.) downloaded data YES! Check the fans of air temp. and relative humidity sensors at Vaira. YES! Check MD-9 system connections YES! Check CR23X with two multiplexers Check levels of Radiation sensors, clear up surfaces. YES! took back the rain gage for checking in the lab (Joe). Closed gate and set up fence. YES! Tonzi_Tower Site Fence and gate power: ok v. Panel and Batteries: ok v; ok amps; ok amps. Reading from Gillsonic screen before downloading data. (The value of H2O and CO2 should be in the range of 0 – 5 v.) downloading data Yes! check the fans of air temp. and relative humidity sensors on the tower and the floor. Yes! Joe moved the rain gage to a new place to reduce influence of bars. Check calibration cylinders; CO2 2100 psig; flow 20 psi. 384.08 ppm N2 1550 psig; flow 20 psi. Manually calibrate Li-800. Following Ted’s instruction: H:\IoneSavanna_2004\Tower_2004\CO2Profile\LI800_Calibration_Procedure_2Nov04.txt Is the pump running‌ Yes!
