Paper Abstract

Direct solar irradiance spectra under clear skies have been carefully measured in a rural station in the region of 'Castilla y Leon' of typical continental climate during 1995 in order to determine the physical and radiative characteristics of atmospheric aerosols in this area. About 300 spectra have been performed with a LI-1800 spectroradiometer with a spectral resolution of 6 nm from 300 nm to 1100 nm and a wavelength sampling of 1 nm. This high-moderate spectral resolution allowed us to retrieve the experimental spectral aerosol optical depth (AOD) using spectral windows of non-absorption modeling it by the Angstrom formula. These modeled AOD spectra was taken, instead of the experimental one, in order to determine the columnar particle size distribution of atmospheric aerosols using the Mie theory and a pseudo-inversion method. We have assumed a monomodal lognormal function with a fixed standard deviation of (sigma) equals 2.5 and two particle refractive indices based on climate characteristics of our continental are of study.
