Top net thermal radiation
WebJan 14, 2009 · The atmosphere directly absorbs about 23% of incoming sunlight, and the remaining energy is transferred from the Earth’s surface by evaporation (25%), convection (5%), and thermal infrared radiation (a net of 5-6%). The remaining thermal infrared energy from the surface (12%) passes through the atmosphere and escapes to space. Webradiation or solar heat gains (Fernandes et al. 2015), simply by using the entire solar spectrum in calculation and the solar material properties instead of those limited
