Abstract
The first of the new generation of Meteosat satellites, known as Meteosat Second Generation (MSG), was launched in August 2002. From its geostationary orbit, the satellite's radiometer, the spinning enhanced visible and infrared imager (SEVIRI), observes the full disk of the Earth with an unprecedented repeat cycle of 15 minutes in 12 spectral channels, having a sampling distance of three kilometres at nadir (1 km for the high resolution channel). For comparison, the first-generation Meteosat satellite covers only three spectral channels and has an imaging repeat cycle of 30 minutes, with a sampling distance between 2.5 and 5 km. MSG offers a wealth of new observational capabilities that could benefit weather forecasting and support severe weather warnings. Significant indirect benefits will come through improved weather forecasts that predict e.g. wind fields more accurately. With the beginning of MSG's operational phase on 29 January 2004, the satellite was renamed to Meteosat-8. The Meteosat-8 operational system also includes a suite of meteorological data which are extracted from the multi-channel image information, as e.g. winds, cloud analysis, atmospheric humidity and atmospheric instability over the entire field of view. This paper presents a general overview over the Meteosat-8 imagery and will especially focus on the meteorological parameters - including the underlying algorithms - that are extracted at EUMETSAT.
