As a main element of China second generation of geostationary meteorological satellite Fengyun 4 （FY-4）, which was launched on Dec. 11, 2016, the Geostationary Interferometric Infrared Sounder （GIIRS） is the first interferometric infrared sounder working on the international geostationary orbit. It is used for vertical atmospheric sounding and gains atmospheric temperature, humidity, and disturbances. The combination of Fourier transform spectrometer technology and infrared detectors makes GIIRS have high spectral resolution and large coverage over spatial areas.
