| On Sunday, 20 May, the tower radiation system became operational. The Temp/RH sensor I installed did not work correctly and will be replaced on my next site visit. Although we are currently logging this data, the MD9/PC208 configuration has not been installed so we do not have pc communication at this time and data must be downloaded manually. The output of the 23x on the tower is as follows: 10 sec execution interval - 30 min averages all values are in milivolts except for the Panel T (degreeC), Batt_Volt (Volts), Temp ambient (degree C) and RH (%) Output ID code Date Time Panel Temp Batt_volt Par_up ave # 990019 5.26 uV/umol/sm2 cal 9Feb99 Par_Dn ave # 990017 5.16 " " " Calib_Par ave # 990021 5.12 " " " Pyranometer ave # 996981 5.03 uV/W/m2 cal 7Sept99 Net_Rad ave #990351 13.9 uV/W/m2 cal 29Jul99 Temp_ambient ave RH ave Par_up std dev Par_Dn std dev Calib_Par std dev Pyranometer std dev Net_Rad std dev Temp_ambient std dev RH std dev Similarly, the net radiation standard was installed at the Vaira site and became operational on Sunday Model CNR1 # 990181 10.19 uV/W/m2 cal 20Aug99 23x output Output ID code Date Time Panel_T (deg C) Batt_Volt (Volt) Net_Rad ave (mvolt) Net_Rad std dev (mvolt) To: Dennis Baldocchi , Lianhong Gu , Nancy Kiang , Liukang Xu FYI Last Sunday 20May I aligned the sonic anemometer on the tower such that its' North indicator line is pointing toward 13 degrees due west of magnetic north. |
