Abstract
The a priori information accumulated on atmospheric aerosols is considered in application to the problems of the analysis of the informativity of measurements of different optical aerosol characteristics for microphysical aerosol parameters. The necessity of modeling the microphysical variations describing the actual aerosol variability is noted. Based on these principles, a statistical microphysical model of ground aerosols is proposed. Using the model, the variational coefficients of optical aerosol characteristics as functions of the microphysical parameters are calculated. They are incorporated into a computer database and the corresponding computation code. The above computational means are applicable for different problems regarding the analysis of the informativity of the measurements of optical aerosol characteristics, in particular, the estimation of the necessary accuracy of simultaneous (test) microphysical ones. As an example, estimates of the informativity of particular lidar measurements are considered for which regression relations between the optical and microphysical parameters were obtained in the framework of numerical experiments. A good agreement between the retrieved aerosol parameters by the proposed regression relations and the corresponding AERONET data has been shown.
