This paper consists in analyzing natural aerosols’ vertical distribution in Sahelian zone via the project called Clouds Seeding Operation (OPEN) in Chad. It is devoted to the study of microphysical parameters, obtained by airborne measurements of aerosols concentrations, and carried out during two air flights: on June 18th, 2014, and November 5th, 2015. This allows studying the variability of their vertical distribution in number, surface and volume. Particles accumulations are studied in different levels according to flight altitude and considered constant at the level where principal physical processes responsible for the rise of the aerosols in the columns of the atmosphere are identified. At these altitudes, the concentrations of aerosols vary in space and time. Results are primarily concerning the granulometric distributions of aerosol particles on various levels and altitudes and the carried out analyses relate to the principal physical processes responsible for the vertical distribution of aerosol particles in the Sahel, and in particular in the areas of the flights of measurement in Chad.

Keywords: aerosols, vertical distribution, Sahel, OPEN project, Chad.
