WebThe National Renewable Energy Laboratory (NREL)'s Renewable Resource Data Center (RReDC) features the following solar resource models and tools that are available for use by the public. ## Bird Clear Sky Model. This algorithm estimates clear sky direct beam, hemispherical diffuse, and total hemispherical solar radiation for horizontal planes. WebThe output of the model is a “clear sky” estimate for the total (global horizontal irradiance: GHI), direct normal irradiance (beam, DNI) and diffuse irradiance across a spectral range … WebAn alternate broadband AOD approximation from Bird and Hulstrom combines AOD measured at two wavelengths [Bir80], and is implemented in bird_hulstrom80_aod_bb(). ...
