Aerosol counts in Venus clouds - Preliminary VEGA 1, 2 density profiles, H = 63-47 KM
Abstract
Results of the preliminary processing of the Vega 1, Vega 2 descenders data on the cloud-layer structure of the Venus atmosphere are discussed. A photoelectric counter for aerosol particles is described together with its optical and pneumatic circuits and operation algorithm. Vertical profiles of concentration of particles with a diameter of 0.4 μm agree qualitatively with the Pioneer-Venus and Venera 9, Venera 10 data. Concentrations of these particles are: in the B layer, up to 1.9×102cm-3; in the C layer, up to 10 cm-3, in the D layer, up to 1.3×102cm-3. Layers have sharp boundaries with significant vertical inhomogeneity of the aerosol concentration field inside them.
