Measures the energy balance between incoming short-wave and long-wave IR radiation relative to reflected short-wave and outgoing long-wave IR radiation
High-output thermopile sensor
Uses two conical absorbers coated in Telflon; one absorber faces up, one faces down
Kipp & Zonen's CNR2 Net Radiometer measures the energy balance between incoming short-wave and long-wave infrared radiation versus surface-reflected short-wave...
Campbell Scientific offers pyranometers, net radiometers, and quantum sensors—all designed to measure various aspects of the energy imparted by the sun on the Earth's surface. A leveling fixture fitted with a "bubble level" is typically required to accurately install solar radiation sensors.
