We present a technique for retrieving ozone concentration profiles via single-wavelength sensing under background aerosol conditions in the upper troposphere and lower stratosphere. At this wavelength, the radiation is considered, corresponding to first Stokes component of transformation of the Nd:YAG laser fourth harmonics (266 nm) in hydrogen (299 nm) on the base of the effect of stimulated Raman scattering. Ozone concentrations were measured in a height range 6-14 km. Based on results of lidar measurements of ozone and the data of aerological sensing of the temperature and humidity, a rather rare process of stratosphere-troposphere transfer through the tropopause was detected in April, 2007 above Tomsk (56.5°N; 85.0°E).
