Abstract
At Siberian Lidar Station (SLS) in Institute of Atmospheric Optics, Siberian Branch of Russian Academy of Sciences, Tomsk (56.5 °N; 85.1°E) we perform regular lidar measurements of the profiles of vertical distribution of optical characteristics of stratospheric aerosol at wavelength 532 nm with receiving telescope of a diameter of 03. m. The temperature profile is measured in the altitude interval 10-70 km: from molecular backscattering signal at wavelength 532 nm in altitude range 30-70 km and from signal of Raman scattering by nitrogen at wavelength 607 nm in altitude range 10-30 km with receiving telescope of a diameter 2.2m. In this paper we analyze the data of long-term (since 1986) lidar observations of stratospheric aerosol layer, performed at Siberian Lidar Station and data of expedition measurements in summer-fall periods of 2001-3003, obtained in Siberian region from middle to subpolar latitudes (from 52° to 69°N and from 73° to 106° E). Main attention is paid to analysis of data of last years of measurements obtained under conditions of “new” background period of long-term absence of explosive volcanic eruptions (last observed in June 1991).
