The instrument GIIRS on-board FY-4A is a hyperspectral sounding instrument, it provides the first IR-sounding observations of earth’s atmosphere in two large bands in the middle and long wave infrared from a geostationary orbit. Its data characteristics are very close to the future IRS instrument on-board the next generation Meteosat Third Generation sounding satellites (MTG-S), therefore both EUMETSAT and ECMWF took the opportunity to work together on a joint study in order to test their data quality analysis capabilities on “real” measurements and prepare the first assimilation of hyperspectral radiances of a geostationary instrument in a NWP model.
