The main goal of this investigation is to develop a kind of “urban reanalysis” – the database of meteorological and radiation fields under Moscow megalopolis with high spatial resolution. Sky View Factor (SVF) is widely used for evaluating the solar irradiance attenuation in urban canopy. In this study we suggested raster-based calculation of SVF. We applied this technique for evaluating specific features in UV irradiance at Moscow megalopolis conditions. We showed that relative frequency of SVF over the territory of Moscow higher than 80% is observed in more than 86% of cases. The maps of UV losses due to sky obscuring over the territory of Moscow have been obtained for different seasons.
