Paper Abstract

The influence of the upper limit λmax of the spectral range in which the atmospheric transmission is measured on the results of retrieval of the aerosol microstructure parameters when solving the inverse problem of sun photometry from the data of numerical modeling and field experiments is investigated. In the numerical experiment the aerosol model comprising fine submicron (f) and coarsely dispersed (c) particle fractions is used. Here λmax is chosen from the range 1.052-3.973 μm. The method of integral distributions is used to solve the inverse problem. It is demonstrated that the limited spectral range causes underestimation of the contribution of large particles to aerosol distributions. In particular, at λmax = 1.246 μm, losses of the retrieved concentration of particles of the c fraction against the background of the decreased (to 18 % at λ = 1.246 μm) volume aerosol concentration can reach 42 %.
