Energy yields of concentrating solar thermal power plants depend strongly on the availability of beam irradiance. Direct solar irradiance is highly variable in space and time and thus, requires in-depth analysis of measurements with high quality, well tracked calibrations and approved quality control to achieve reliable results. Strong vari-ability from year to year makes it necessary to combine precision data, available from limited measurement peri-ods with long-term data, which should cover at least 10 years. For most places this may only be reached by ap-plication of historic satellite data. For sites around the Mediterranean region, Africa and the Mideast solar prod-ucts based on data from the Meteosat First Generation so far have been used. Since mid 2006 this satellite gen-eration is out of service and replaced by Meteosat Second Generation. Therefore, recent measurements can not be inter-compared to the satellite-series, which is used to retrieve long-term time-series. In this paper, a satellite-retrieval for beam irradiance from the new generation is introduced and inter-compared with data derived from the first generation satellite for an over-lapping 2 year time period. Applying more than one satellite data set has the further advantage to incorporate several independent data sets and thus strengthens credibility of the final result. A new procedure which combines the value of independent data sets is introduced: A quality-weighted average is produced depending on the individual uncertainties of each data set. By the help of long-term data the most representative climatological values are determined for the final best estimate, which is required for bank-able simulations of energy yields.
