Solar Stray Light Effects in Meteosat Radiances Observed and Quantified Using Operational Data Monitoring at ECMWF
|
ABSTRACT
Radiances in the water vapor (WV) and infrared channels of the Meteorological Satellite (Meteosat)-5 and -7 are being continuously monitored in the form of clear-sky radiances using the operational European Centre for Medium-Range Weather Forecasts (ECMWF) data assimilation system. The clear-sky radiances are provided by the European Organization for the Exploitation of Meteorological Satellites (EUMETSAT), using their scenes analysis to eliminate pixels affected by clouds. Th...
