Satellite-derived solar resource map As solar radiation passes through the earth’s atmosphere, some of it is absorbed or scattered by air molecules, water vapour, aerosols, and clouds. The solar radiation that passes through directly to the earth’s surface is called direct solar radiation. The radiation that has been scattered out of the direct beam is called diffuse solar radiation. The direct component of sunlight and the diffuse component of skylight falling together on a horizontal surface make up global solar radiation.
