Tower height: 320 cm from ground to mid-sonic. Sonic N pointed at 331 N magnetic. Ground water well installed. Bottom of pressure sensor 110 cm below top of pipe. Top of pipe 65cm above ground. Water height was 10 cm above ground. Need to install DO sensor. Also need more wipes for water sensors. Wasp nest in end of rad boom. Need wasp spray. Downloaded data. Swapped IRGA. Removed sn 75H-2150, installed sn 75H-2514. Readings after swap: CO2 = 400 ppm H2O = 430 mmol m-3 signal strength = 100.48% p = 101.1 kPa t = 18 C sos: 343.5 m s-1 CH4 = 1.9 ppm variable RSSI = 61% Topped off reservoir. Cleaned Rad. Met looked good, except soilT2_02 and WaterT_3 were –INF. |
