Vertical structure of Venusian cloud layer at landing sites of Vega-1 and Vega-2 vehicles
Abstract
The objective of the Vega experiment was a study of parameters of aerosols in the Venusian atmosphere (particle size distribution and concentration of aerosols, shape of particles and refractive index of their material). Pioneer-Venus data seemed to indicate that the main cloud layer consisted of three types of particles forming three modes, the modal diameter of the third type being about 7.3 microns, asperical particles of unknown composition. The first mode is described by a Junge distribution from 0.5 to 5 microns and the second mode consists of particles measuring 2 to 5 microns.
