1Satellite-based Data Sets for EURO4M Jörg Trentmann, Uwe Pfeifroth, Jennifer Lenhardt, Richard MüllerDeutscher Wetterdienst (DWD)
2Satellite-based data sets to be generated and delivered within EURO4M Surface Solar RadiationCloud FractionSurface AlbedoPrecipitationIntegrated Water VaporAll data sets are provided as monthly means in netcdf-format for the European Domain: 20W – 40E, 30N – 75N
3Surface Solar Radiation a) Global Radiation (Irradiance)Based on Meteosat1983 – 20100.05 deg spatial resolutionAccuracy better than 10 W/m2Homogeneous after 1995ApplicationsClimate MonitoringSolar Energy/Agricultural ApplicationsReanalysis evaluation
4Surface Solar Radiation b) Global Radiation (Irradiance)Based on AVHRR1982 – 20090.25 spatial resolutionAccuracy better than 10 W/m2ApplicationsClimate MonitoringSolar Energy/Agricultural ApplicationsReanalysis EvaluationData availableResults from modified retrieval of solar radiation currently under investigation,Merging of different data sets possible
5Cloud Fraction Cloud Fraction Based on AVHRR 1982 – 2009 ApplicationsClimate MonitoringReanalysis EvaluationSolar Energy Applications etc.Cloud FractionBased on AVHRR1982 – 20090.25 spatial resolution
6Surface Albedo Surface Albedo based on AVHRR 1982 – 2009 0.25 spatial resolutionApplicationsClimate MonitoringReanalysis EvaluationSnow Monitoring, etc.
7Surface Precipitation based on GPCC / HOAPS 3.21987 – 20080.5 deg spatial resolutionApplicationsClimate MonitoringReanalysis EvaluationHydrological Modeling, etc.
8EURO4M Precipitation vs. GPCP High spatial resolutionGPCP overestimates surface precipitation in Europe
9Integrated Water Vapor Based on ATOVS1999 – 2010approx. 1 deg resolutionApplicationsClimate MonitoringReanalysis Evaluationetc.
10Summary Selected satellite data sets already available Partly used already for evaluation of EURO4M reanalysis dataSurface Solar radiation data set will be further assessedData available via ftp-server upon request:
