4-Component Net Radiometer

1. 4-Component Net Radiometer Product Overview

4-Component Net Radiometer measures the net difference between the amount of full-wave radiation projected downward from the sky and upward from the Earth's surface.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 is emitted by all objects on Earth. The spectrum of the sun's short-wave radiation is from 300 nm to 3 μm (accounting for 99.5% of the total solar radiation).

Fengtu's FT-FS7H four-component net radiation sensor directly measures daily longwave radiation and shortwave radiation and calculates the net radiation. It is used for meteorological observations of atmospheric radiation (radiation emitted by clouds/water vapor and carbon dioxide, etc.) and net radiation exchange between the earth and the atmosphere. Net total radiation (shortwave + longwave) is usually measured by 4 net radiometers or a single net radiometer (whose detector can respond to the full band). The earth's longwave radiometer uses a detector with a hemisphere facing upward to measure the longwave radiation emitted downward. The net longwave radiation and the downward emitted radiation of the earth-atmosphere system can be calculated. It has been widely used in meteorology/photovoltaics/horticulture/agriculture and industry.
