1、 Product Overview
In meteorological applications, infrared radiation or longwave radiation refers to electromagnetic radiation with wavelengths greater than 3.0 μ m. Long wave radiation is physically related to temperature, and all objects on Earth emit long wave radiation. The spectral range of short wave radiation from the sun is 300nm to 3 μ m (accounting for 99.5% of the total solar radiation energy).
Four component radiometerBy directly measuring daily longwave and shortwave radiation and calculating the net radiation level. Meteorological observations for atmospheric radiation (radiation emitted by clouds/water vapor, carbon dioxide, etc.) and net radiation exchange between the Earth and the atmosphere. Net total radiation (shortwave+longwave) is usually measured by four net radiation meters or a single net radiation meter (whose detector can respond to the entire frequency band). The Earth's longwave radiation meter uses a hemisphere facing detector to measure longwave radiation emitted downwards. The net longwave radiation and downward emission radiation from the Earth atmosphere system can be calculated. It has been widely used in fields such as meteorology, photovoltaics, horticulture, agriculture, and industry.
