摘要:The use of solar radiation measurements on various solar systems design needs knowledge on its spatial and temporal variations. Such knowledge can be acquired by employing interpolation ground measured solar radiation collected by ground radiometric stations. More reliable information could be obtained by analyzing satellite images. The aim of this work is to evaluate the measurements of daily global solar radiation extracted from Meteosat-8 images using Heliosat-2 method. Ground measurements from two Iraqi stations were used in the evaluation processes. The results indicated that the mean RMSE and MAE for Baghdad were 0.621 kWh/m2 and 0.024 kWh/m2 and for Mosul were 0.458 kWh/m2 and 0.012 kWh/m2 respectively. These results are very satisfactory for monitoring the temporal and spatial variation of solar radiation for places which suffer from shortage of ground solar radiation measurements.
