Short summary

The new CAMS (Copernicus Atmosphere Monitoring Service) McClear service is a practical easy-to-use tool to estimate the solar direct and global irradiances received at ground level in cloud-free conditions at any place any time. This article presents validation against 1 min measurements made at three very close stations in Israel in desert conditions. The good results demonstrate the accuracy of McClear and its ability to capture the temporal and spatial variability of the irradiance field.
