Review of Geostationary Interferometric Infrared Sounder
To measure the global atmospheric 3-dimensional distribution and change of temperature and humidity is one of the key areas in atmospheric remote sensing detection, it is also a new research and development direction in the field of meteorological satellite application. As a main element of China second generation of geostationary meteorological satellite FY-4 which was launched on Dec.11, 2016, Geostationary Interferometric Infrared Sounder (GIIRS) is the first interferometric infrared sounder working on geostationary orbit internationally. It is used for vertical atmospheric sounding and gains atmospheric temperature, humidity and disturbances. The combination of Fourier transform spectrometer technology and infrared detectors make GIIRS to have high spectral resolution and large coverage over spatial areas. With this kind of instrument, meteorological satellites can improve the capabilities for severe weather event monitoring and numerical weather prediction. In this paper a concise review of the GIIRS development project, including its history, missions and functions, technical design, key technologies, system integration, calibration and in-orbit operation status, etc. is presented.
