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 (%)

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

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.
