2. Satellite-based data sets to be generated and delivered within EURO4M
Surface Solar Radiation
Cloud Fraction
Surface Albedo
Precipitation
Integrated Water Vapor
All data sets are provided as monthly means in netcdf-format for the European Domain: 20W – 40E, 30N – 75N

3. Surface Solar Radiation
a) Global Radiation (Irradiance)
Based on Meteosat
1983 – 2010
0.05 deg spatial resolution
Accuracy better than 10 W/m2
Homogeneous after 1995
Applications
Climate Monitoring
Solar Energy/Agricultural Applications
Reanalysis evaluation

4. Surface Solar Radiation
b) Global Radiation (Irradiance)
Based on AVHRR
1982 – 2009
0.25 spatial resolution
Accuracy better than 10 W/m2
Applications
Climate Monitoring
Solar Energy/Agricultural Applications
Reanalysis Evaluation
Data available
Results from modified retrieval of solar radiation currently under investigation,
Merging of different data sets possible

5. Cloud Fraction Cloud Fraction Based on AVHRR 1982 – 2009
Applications
Climate Monitoring
Reanalysis Evaluation
Solar Energy Applications etc.
Cloud Fraction

1999 – 2010
approx. 1 deg resolution
Applications
Climate Monitoring
Reanalysis Evaluation
etc.

10. Summary Selected satellite data sets already available
Partly used already for evaluation of EURO4M reanalysis data
Surface Solar radiation data set will be further assessed
