Spectrometer measurements of the aerosol particle-density profiles above the Vega 1 and Vega 2 landing sites generally confirm the height-zone structure found in earlier sounding of the Venus atmosphere: a three-layer main cloud deck, an intermediate zone, and a subcloud haze region. However, the Vega results show substantial differences in the number density and especially the size spectrum of the aerosols. A tropospheric nightglow is present at wavelength of about 1 micron. The backscatter and extinction coefficients undergo relatively little variation over the 63-32 km height range. Submicron atmospheric particles appear to be abundant above the landing sites.
