Serial Number Range 0-10516. Example of total shortwave
radiation measurement with an Apogee SP-212
pyranometer. Full sunlight yields total shortwave radiation
on a horizontal plane at the Earth's surface of
approximately 1000 W m
2000 mV. The signal is converted to shortwave radiation by
multiplying by the calibration factor of 0.5 W m
