Short summary

Several satellite-derived solar surface irradiance databases provide long-term and homogeneously distributed information on the solar potential at ground level. This paper presents the validation results of three of these databases: HelioClim-3 (versions 4 and 5) and the CAMS radiation service, versus the measurements of 42 stations in Brazil. Despite a slight overestimation of the CAMS radiation service, the three databases are suitable for studies of the solar resources in Brazil.
