Аннотация
Features of determining the aerosol microstructure from spectral measurements of the aerosol optical depth are considered in the context of little information concerning the solution in the region of large particles. Such conditions are implemented in the cases where the aerosol contains particles whose dimensions much exceed the measurement wavelengths. A modified algorithm involving the hybrid model of the aerosol microstructure is proposed for the inversion of the aerosol optical depth. The model includes the description of the dispersion composition of aerosol in the informative region of the size based on the integral distribution function. The description is completed by the parametric representation of the microstructure of large particles. The efficiency of the developed algorithm is studied by numerical simulation. Results of the algorithm approbation in the inversion of field experiment data are presented. They demonstrated the possibility to reconstruct microstructure parameters of the coarse fraction of aerosol when the upper boundary of the spectral range is decreased from 4 to 1.56 μm.
