4-Component Net Radiometer

1.4-Component Net Radiometer Product Overview

4-Component Net Radiometer measures the energy balance between incoming shortwave and longwave infrared radiation and the shortwave reflected by surfaces.In meteorological applications, infrared radiation or long-wave radiation refers to electromagnetic radiation with a wavelength greater than 3.0 μm.Long-wave radiation is physically related to temperature and all objects on Earth emit long-wave radiation.The spectral range of the sun's short-wave radiation is 300nm to 3μm (accounting for 99.5% of the total solar radiation energy).

Fengtu's FT-FS7H four-component net radiation sensor directly measures the daily long-wave radiation and short-wave radiation and calculates the net radiation.Meteorological observations for atmospheric radiation (radiation emitted by clouds/water vapor and carbon dioxide, etc.) and net radiation exchange between the earth and the atmosphere.The net total radiation (short wave + long wave) is usually measured by 4 net radiation meters or a single net radiation meters (the detector can respond to the full band).The Earth's long-wave radiation meter uses a hemisphere-facing detector to measure the long-wave radiation emitted downward.Net long-wave radiation and downward emission radiation from the ground gas system can be calculated.It has been widely used in the fields of meteorology/photovoltaics/horticulture/agriculture and industry.
