As the world's most abundant renewable resource, solar energy is expected to play a key role in the future global energy supply. Given the fluctuating nature of solar irradiation, its efficient use requires reliable measurement and forecasting its availability on several temporal and spatial scales, depending on the application. This paper validates previously published clear sky models which accurately estimate solar irradiation data using aerosol optical depth (AOD) measurements. The validated clear sky models presented can be useful tools for confirming the goodness of both global horizontal and direct normal irradiation measurements. It also proposes a simple method for predicting irradiation by means of irradiation measurements and forecast AOD. Moreover, measured AOD is shown to be required for prediction, as estimation of DNI using satellite-derived AOD data has been found to be inaccurate.
