NR-LITE Net Radiometer
5.3.2 CR1000 Example Program with Wind Speed Correction
Shown below is an example program written for the CR1000 datalogger.
Besides measuring the NR-LITE, the program also measures wind speed and
applies the correction factor as described in Section 1.4. Average net radiation
and wind speed are output every hour.
