The high-altitude satellite 5 atmospheric environment detection load is officially delivered

[ China Instrument Network Instrument Development ] On March 21, the Ministry of Ecology and Environment, China Meteorological Administration, China Satellite Launch Measurement and Control System and other user units signed a high-input satellite in-orbit certificate for use in Beijing, which marked the high score. The atmospheric environment detection load of the No. 5 satellite is officially delivered.

The high-scoring satellite No. 5 is China's first full-spectrum hyperspectral remote sensing satellite that realizes comprehensive observations of the atmosphere and land. It has successfully completed all on-orbit testing tasks. The high-scoring No. 5 satellite carries a total of six loads, including three main load atmospheric trace gas differential absorption spectrometers (EMI) for atmospheric environmental detection, atmospheric major greenhouse gas monitors (GMI), and atmospheric aerosol multi-angle polarization detection. The instrument (DPC) was undertaken by the Anhui Institute of Optics and Fine Mechanics of the Chinese Academy of Sciences. The three load pins mainly provide fast and accurate global information acquisition of sensitive components of the Earth's atmosphere, thus achieving comprehensive detection of major atmospheric pollutant gases, greenhouse gases, clouds and aerosols.

On May 9, 2018, the high-altitude satellite No. 5 was successfully launched as China's first high-resolution atmospheric environment observation satellite. Three atmospheric environmental detection loads were launched during the month, and for the first time in the orbit test, China acquired atmospheric trace gases. The global distribution of nitrogen dioxide, etc., the use of a new technology system of the main atmospheric greenhouse gas monitor (GMI) to obtain accurate greenhouse gas spectral data; as the world's only operational in the orbit of the use of polarization technology to detect aerosols The satellite acquired multi-spectral and multi-angle polarized images and successfully inverted global aerosol and optical aerosol products on the land and ocean and cloud phase classification products. On December 21, 2018, the atmospheric environment detection load passed the on-orbit test summary review organized by the Aerospace Eighth Environmental Satellite Project Office.

The user bases of the Satellite Environment Application Center of the Ministry of Ecology and Environment, the National Satellite Meteorological Center of the China Meteorological Administration, and the Ministry of Environmental Protection confirmed that all the three load indicators met or exceeded the technical requirements of the test specifications, while using the high-point satellite atmosphere. Trace gas differential absorption spectrometer (EMI) data products, atmospheric aerosol multi-angle polarization detector (DPC) and atmospheric main greenhouse gas monitor (GMI), the global ozone, nitrogen dioxide and other trace gas distribution, ash Pollution distribution and inversion studies of atmospheric greenhouse gases. The user unit realized the remote sensing quantitative inversion of ozone, nitrogen dioxide, sulfur dioxide, PM2.5 concentration, ash pollution, carbon dioxide and methane distribution to produce thematic products. Through comparison and analysis with international gas inversion products of similar loads, the user unit believes that the inversion accuracy of EMI and GMI loads is high, reaching the international advanced level of similar loads, and carrying out monitoring of ozone, nitrogen dioxide, sulfur dioxide, carbon dioxide and methane. The application capability of the stage evaluation; DPC payload is the only satellite remote sensor in the world that can detect the aerosol by using polarization technology. It has stable performance, clear image, strong stray light suppression ability and data with various types of gas. Production capacity of sol and cloud products.

After the high-point No. 5 satellite atmospheric environment detection load is officially delivered, it will formally provide applications, provide important scientific and technological support and space information services for China's environmental pollution prevention and control work, and improve the level of quantification and refinement of atmospheric remote sensing monitoring in China.
