Kaspar frank.kaspar@dwd.de R. Hollmann M. Lockhoff K.-G. Karlsson A. Dybbroe P. Fuchs N. Selbach D. Stein J. Schulz Satellite Application Facility on Climate Monitoring, Deutscher Wetterdienst, Offenbach, Germany Swedish Meteorological and Hydrological Institute (SMHI), Norrköping, Sweden The Satelite Application Facility on Climate Monitoring has implemented a new processing environment for AVHRR-based climate monitoring products. AVHRR measurements from NOAA-17, NOAA-18 and MetOp-A are utilized to generate daily and monthly means of several cloud parameters for Europe and the Inner Arctic: Cloud fraction, cloud types, cloud phase, cloud top height, cloud optical thickness and cloud liquid water path.
