CNR1 Net Radiometer
6.2.3 Example 3, CR23X Program Using Differential Channels
Program Example 3 requires six differential channels and the 4WPB100
module to measure the four radiation outputs and the Pt-100 temperature
sensor. The program measures the sensors every 2 seconds and calculates and
stores the following data to final storage every 60 minutes:
Array ID
Year
Julian
Day
Hour/Minute
Avg CM3 Up (shortwave radiation)
Avg CM3 Down (shortwave radiation)
Avg CG3 Up (longwave radiation)
Avg CG3 Down (longwave radiation)
Avg CNR1 temperature (degrees C)
Avg CNR1 temperature (degrees K)
Avg Net shortwave radiation
Avg Net longwave radiation
Avg Albedo
Avg Total Net radiation
Avg temperature corrected CG3 Up
Avg temperature corrected CG3 Down
