GF-5 (02)'s Four Satellite Payloads Release DEMO Design

Mar 22, 2019

The formal DEMO design of the four atmospheric environment detection payloads on GF-5 (02) was released by Anhui Institute of Optics and Fine Mechanics (AIOFM), Hefei Institutes of Physical Science of Chinese Academy of Sciences (CASHIPS) in Hefei on March 19, 2019, and the DEMO has unanimously passed the review.

The four payloads on the satellite, developed by AIOFM, comprise 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). They are all for atmospheric environment detection.

The POSP, mainly to detect the atmospheric fine particles, aerosols/clouds, and water vapor, is a newly-developed system. 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, this 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 its strong ability to multi-spectral full polarization detection.

Therefore, POSP will foster 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 the quantification and refinement level of atmospheric remote monitoring as it realizes accurate and quantitative monitoring of the temporal and spatial distribution information for atmospheric aerosols, atmospheric gases tracing as well as other greenhouse gases.
