Abstract

We present the dynamics of stratospheric aerosol characteristics after the Mt. Pinatubo eruption. Measurements were carried out with a lidar, which has been operating at 532 and 1064 nm wavelengths. An approach to the processing of two-wavelength polarization sounding data is presented. Altitude-temporal dependence contours of the aerosol backscatter ratio, the ratio of aerosol backscatter coefficients at two wavelengths, and the aerosol linear depolarization ratios are given. Possible temporal transformations of the stratospheric aerosol microstructure characteristics that cause the changes in optical parameters are discussed.
