Abstract

Satellite observations and chemical transport models used for the derivation of Aerosol Optical Depth (AOD) values have an extensive coverage worldwide and are widely used when ground-measured AOD is not available. However, satellite and modelled values present high uncertainties and cannot be always considered reliable especially at the level needed for solar radiation modelling. This work presents a methodology for calibrating existing AOD databases, which are commonly used as inputs to clear sky models for estimating clear-sky solar irradiances. This methodology makes use of ground-measured direct normal irradiance (Hb), integrated backscatter profiles of a lidar-ceilometer device, and Hb calculated from clear sky models with different AOD databases.
