Estimation of the real-sky total solar irradiation for the Werenskjold glacier (SW Spitsbergen) with the r.sun model

Abstract

The r.sun model was applied to assess the spatial and temporal changes in incoming total (beam + diffused) real sky radiation. Presented approach accounts for aerosol, precipitable water content and cloudiness effects on attenuation of solar radiation. The results are compared with the measurements gathered at Polish Polar Station, showing good agreement
