Paper Abstract

Lidar measurements of geometrical (height, thickness) and radiative properties (extinction and backscattering) of the volcanically perturbed stratospheric aerosol layer are presented and discussed. The layer is located between about 12 and 25 km height. Since December 1991 the particle optical depth is between 0.1 and 0.2 for the wavelength of 0.5 micron. The determined extinction-to-backscatter, or lidar, ratios of 10 to 40 sr indicate an increase of the mean radius of the stratospheric sulfuric acid droplets compared to the respective value for the background distribution.
