Summary: Tower radiation system operational. Sonic alignment.

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 sn 990019 5.26 uV/umol/sm2 cal 9Feb99 Par_Dn ave sn 990017 5.16 " " " Calib_Par ave sn 990021 5.12 " " " Pyranometer ave sn 996981 5.03 uV/W/m2 cal 7Sept99 Net_Rad ave sn 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 sn 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) Last Sunday 20May Ted aligned the sonic anemometer on the tower such that its' North indicator line is pointing toward 13 degrees due west of magnetic north. Hi Dennis - the declination I used to set the orientation of the tower sonic was that for Laramie, Wyoming. The true declination for our site is listed below - I missed by 2 degrees 19 min Canadian Geomagnetic Reference Field (CGRF) REQUESTED: The magnetic declination in 2001 at Latitude 38 ° 24' N Longitude 120 ° 57' W : CALCULATED: The magnetic declination in 2001 at Latitude 38 ° 24' N Longitude 120 ° 57' W: 15º 19' E
