Solar Radiation

Instrument Type: LI-Cor LI200SZ Pyranometer Sensor

Installed: 8 January 2015

Description: Silicon photodiode sensor calibrated to measure total radiation received from the sun; cosine-corrected to make the sensor insensitive to the direction of the radiation within the forward hemisphere.
