CNR1 Net Radiometer

The CNR1 Net Radiometer is intended for the analysis of the radiation balance of Solar and Far Infrared radiation. The most common application is the measurement of Net (total) Radiation at the Earth's surface. The design is such that both the upward-facing and the downward-facing instruments measure the energy that is received from the whole hemisphere. The output is expressed in Watts per square meter. The design is such that Solar radiation and Far Infrared radiation are measured separately. Solar radiation is measured by two CM3 pyranometers, one for measuring incoming solar radiation from the sky, and the other, which faces downward, for measuring ther reflected Solar radiation. From these two pyranometers, albedo, known as the ratio of reflected and incoming radiation , can also be determined.
