[ Instrument Network Instrument R&D ] As of July 3, 2020, the high-resolution major special common key technology research project "GF-5 high-precision multi-angle polarization data high-precision inversion technology" undertaken by the Optical Remote Sensing Research Center of Anguang Institute, And two high-scoring major special common key technology research projects jointly undertaken with the National Meteorological Satellite Center of China Meteorological Administration "GF-5 aerosol retrieval technology based on multi-angle polarization" and "GF-5 greenhouse gas detector data fine processing "Technical research" successfully passed the project acceptance organized by the Major Special Engineering Center of the National Defense Science and Technology Bureau in Beijing, and the expert group fully affirmed the project results.

Atmospheric Aerosol Multi-angle Polarization Detector-Retrieved results of aerosol optical thickness in China on October 2, 2018

The main greenhouse gas monitors in the atmosphere-atmospheric CO2 and CH4 observation accuracy

The "GF-5 high-precision multi-angle polarization data high-precision inversion technology" project aims at the data requirements of the GF-5 satellite atmospheric aerosol multi-angle polarization detector load application, and overcomes the high-precision multi-spectral, multi-angle, and polarization image configuration. Quasi-key technology, high-precision registration results of large-field multi-angle polarization images were obtained, and demonstration operations in typical areas were realized.

The "GF-5 aerosol retrieval technology based on multi-angle polarization" project developed a multi-spectral and multi-angle polarization aerosol retrieval algorithm based on the data from the GF-5 satellite atmospheric aerosol multi-angle polarization detector, and obtained atmospheric aerosols Satellite observations have realized the demonstration operation of regional aerosol inversion in China.

In the "GF-5 Greenhouse Gas Detector Data Fine Processing Technology Research" project, Anguang Research Institute designed a hyperspectral high-quality data processing method for the spatial heterodyne interference data of the greenhouse gas detector, and developed the CO2/ The CH4 comprehensive inversion algorithm obtained the global atmospheric CO2/CH4 satellite observation results of the greenhouse gas detector, and served the CO2 spatiotemporal assimilation model developed by the project to realize the demonstration operation of the regional assimilation system in China.

The related algorithm software developed by the above projects have been tested and applied in the National Satellite Meteorological Center, the main user unit of GF-5 satellite data, and the Satellite Environment Application Center of the Ministry of Environmental Protection and Ecology. The research results of the project promoted the application of Gaofen-5 satellite data in atmospheric aerosol and greenhouse gas monitoring.
