| Sumario: | The study of solar radiation is a key process for the exploitation of solar energy systems. In most cases, however, the availability of information is insufficient and not up-to-date. In addition, the interpolation of ground-level measurement stations data does not allow the observation of microclimatic aspects of solar radiation (Zelenka at al., 1999). Therefore, a statistical model and NOAA-AVHRR satellite images were selected for the determination of solar radiation maps for the entire Iberian Peninsula. The statistical methodology based on Diabate et al. (1989) and Flores (2002) assures the accuracy of the process and the NOAA-AVHRR images provide a fine high resolution of 1 km2, which is needed because of the complexity of the area of study. The period of study covers five years (1998-2002), which assures the study of the year-on-year variation of solar radiation. The statistical model was calibrated with data from 21 ground-level measurement stations all around the Iberian Peninsula. These data were filtered with the aim of eliminating all erroneous registers, which a crucial subject in the method. The satellite images were geometrically calibrated and corrected. Furthermore, a methodology for the detection of clouds was applied in order to obtain the surface albedo (Laine et al., 1999). The evaluation of results, with 7 independient ground-level measurement stations, leads to a MBE of −3.8% and a RMSE of 24.4% for the daily data and a MBE of −1.1% and a RMSE of 15.9% for the hourly data. Maps of hourly and daily solar radiation for the years of study and the average tendency were determined. The Iberian Peninsula receives a mínimum of 4.2 MJm−2 d−1 and a maximum of 26 MJm−2 d−1 of dailly solar radiation, whith a mean of 15.1 MJm−2 d−1. The year-to-year variability of solar radiation ranges between 14.9 MJm−2 d−1 for year 2002 to 17.3 MJm−2 d−1 for year 2000. The results clearly show the usefulness of this work when obtaining solar radiation maps with a high temporal (hourly and daily maps) and spatial resolution (1 km2). |
