This page demonstrates prototype results of the inter-comparison of equivalent infrared channels of geostationary Meteosat imagers and the polar-orbiting IASI sounder from collocated observations. The data will be updated twice every 5 days, around 0700UTC. The activity is an important milestone toward an operational GSICS. Similar activities are currently pursued by other GSICS participants. The results, using the inter-calibration algorithm, can also be downloaded as Statistical Data, in NETCDF Format, from EUMETSAT's GSICS Data and Product Server. The results for 2007 were analysed by Hewison and König, 2008 (See Inter-Calibration of Meteosat Imagers and IASI from the Proceedings of the EUMETSAT Satellite Conference, Darmstadt, Germany, September 2008).
