This paper presents the results of numerical calculations of the vertical profiles of the micrometeorite number density in the mass range from 10 to 10 g. Profiles of the atmospheric relative turbidity at wavelengths of 0.1 and 0.5 mm for the altitude range 30 to 110 km are also calculated. The effect of eddy diffusion is noticeable only for the smallest micrometeorites (m ≤ 10 g) below 60 km.
