| Abstract: | Based on mathematical simulation, quantitative estimates of the effect that coarse dust particles have on the accuracy of
retrieving the optical characteristics of aerosol have been obtained from the results of ground-based measurements of the
spectral fluxes of both direct and scattered solar radiations. The results of verifying a retrieval algorithm (used at the
AERONET ground-based network) based on special test models showed that the aerosol characteristics retrieved with this algorithm
are unsuitable for calculating integral solar fluxes and for simulating space spectrometric IR measurements when the concentration
of dust particles in the atmosphere exceeds their concentration in the well-known CONT model of continental aerosol by a factor
of two or more. |
