Parameterization of solar irradiation under clear skies Mächler, Meinrad A.
Abstract
This study compares 5 existing insolation models on three levels of complexity. The model by Leckner represents a spectral integration model, the models by Bird & Hulstrom, Davies & Hay and by Hoyt are parameterization models and the model of A.S.H.R.A.E is a simple seasonal model. The emphasis of the comparison was kept on the attenuation by atmospheric aerosols as well as on the aspect of the scattered radiation. No new model will be proposed; instead, several improvements to increase the accuracy or to make the application easier will be presented, notably for the determination of aerosol attenuation. Simplification has been achieved by using the correlation between horizontal ground visibility and aerosol attenuation, resulting in easy-to-handle equations. While most models received only minor changes it was necessary to restructure the A.S.H.R.A.E. algorithm substantially.
