The assimilation of FY ‐ 4B Geostationary Interferometric Infrared Sounder long‐wave radiances in the China Meteorological Administration Global Forecast System
The Geostationary Interferometric Infrared Sounder (GIIRS) is the world's first hyperspectral infrared sounder to operate in geostationary orbit, carried on the FY‐4 series of satellites. This study aims to prepare and evaluate the assimilation of FY‐4B GIIRS long‐wave radiances in the China Meteorological Administra...
