A four-component radiometer

1.Product overview of four-component radiometer

A four-component radiometer is a high-precision instrument that calculates net radiation by directly measuring short - and long-wave radiation.In meteorological applications, infrared radiation or long-wave radiation refers to electromagnetic radiation with a wavelength greater than 3.0 μm. Longwave radiation is physically related to temperature and is emitted by all objects on Earth. The spectral range of the sun's shortwave radiation is 300nm ~ 3μm (accounting for 99.5% of the total solar radiation energy).

Fengtu's FT-FS7H four-component net radiation sensor directly measures daily long-wave radiation and short-wave radiation and calculates the net radiation amount. For meteorological observations of atmospheric radiation (radiation emitted by clouds/water vapor, carbon dioxide, etc.) and the net radiation exchange between the Earth and the atmosphere. Net total radiation (shortwave + longwave) is usually measured by 4 net pyranometers or a single net pyranometer (its detector can respond to the entire wavelength range). Pyranometers measure downward emitted longwave radiation using a detector with a hemisphere pointing upward. The net longwave radiation and the downward emitted radiation from the earth-atmosphere system can be calculated. It has been widely used in the fields of meteorology/photovoltaic/horticulture/agriculture and industry.
