PREDICTING THE BROADBAND AEROSOL TRANSMITTANCE FOR SOLAR RADIATION MODELS

Based on a detailed spectral aerosol model (1), the total scattering and absorption broadband aerosol transmission functions are estimated. Using parameterization techniques, analytical expressions for the broadband aerosol transmission functions are obtained. The accuracy of the proposed expressions are verified with various tests. The proposed broadband aerosol transmission functions can be combined directly with the solar radiation models to predict accurately the direct beam, the diffuse and the total solar radiation at a given place.
