GF-5 (02)'s Four Satellite Payloads Release DEMO Design TEXT SIZE: A A A
Date:2019.03.22 Author:YAN Jing Clicks:

Anhui Institute of Optics and Fine Mechanics (or AIOFM), Hefei Institutes of PhysicalScience (or CASHIPS) released the formal DEMO design of the four atmospheric environment detection payloads on GF-5 (02) and the DEMO passed unanimously the review, as the review meeting was held in Hefei on 19 March, 2019.

According to AIOFM, CASHIPS, who untertakes the mission of developing four payloads on GF-5 (02), the four payloads equipped on the satellite are aimed for atmospheric environment detection, and are composed of Environment Monitoring Instrument (EMI- II), the Greenhouse gases Monitoring Instrument (GMI-II), the Directional Polarization Camera(DPC-II)) , and the atmospheric Particulate Observing Scanning Polarimeter (POSP).

And the POSP among the four is a newly-developed system with the hope to detect the atmospheric fine particles, aerosols/clouds, water vapor and so on. It could work closely with atmospheric aerosol multi-angle polarization detectors through multiple working channels from the ultraviolet to short-wave infrared spectrum.

In addition, with its strong ability to multi-spectral full polarization detection, the newly-developed system possesses the function for fusion of surface data transmission and polarization data then to obtain high-precision polarization detection data of atmospheric aerosols.

With those functions above, POSP fosters air quality monitoring with data support ranging from aerosol conventional monitoring to fine particle inversion basic input.

The four satellite payloads are expected to further improve China’s the quantification and refinement level of atmospheric remote monitoring by since it realizes accurate and quantitative monitoring of the temporal and spatial distribution information for atmospheric aerosols, atmospheric gases tracing as well as other atmospheric greenhouse gases.
