A general formulation of the problem of calculating the altitude behavior of the concentration of primary cosmic-dust particles (micrometeorites) with different masses in the diffusion-sedimentation model, i.e., taking into account the magnitudes of the particle influx, sedimentation, and turbulent mixing of the atmosphere, is presented. Numerical calculations for the purely sedimentation model were performed. It is shown that particles with masses of 10-16 ...10-14g make the largest contribution to aerosol scattering of radiation with wavelengths of 0.1...0.5 μm. However the relative atmospheric turbidity produced by them is small: it does not exceed 2% of the Rayleigh molecular scattering.
