Solar Radiation Sensor
The solar radiation sensor measures global solar radiation, which is the primary energy source for snowmelt processes. Solar radiation varies significantly among regions, season, and time of day. Surrounding terrain elevation, man-made obstructions, and surrounding trees can also cause large variations in locations with a small area.
The Li-Cor pyranometer is designed for field measurement of global solar radiation, featuring a silicon photovoltaic detector mounted in a fully cosine-corrected miniature head. The current output is directly related to solar radiation.
