5. Conclusion
This method enables the determination of the
incoming solar radiation reaching the ground by
evaluation of satellite data. The mean accuracy for
monthly averages is about 110 J/cm 2 (spatial
resolution in subsatellite point: (5km) 2 ). Because
this method can be easely applied to datasets of
different geosationary satellites (so far Meteosat
and GMS) it is feasible to prepare maps of global
radiation over the entire globe. For this effort
the B3 - dataset of the ISCCP can be used.
