Abstract:
The paper analyzes experimental data on variations of vertical-temporal structure of aerosol, which were obtained using lidar complex of the small station of high-altitude atmospheric sensing (SSHAS) IAO SB RAS for the period 2010-2011. A characteristic feature of this period was almost no volcanic activity with emissions to the stratosphere. This made it possible to study the behavior of the vertical structure of the background aerosol in the stratosphere on a monthly basis for certain nights during two years. The analysis of the results revealed differences in the vertical stratification of aerosol between 2010 and 2011. For 2010, the aerosol loading was maximal in January up to heights of 30 km, it diminished starting from February until almost no decrease in March-August, and showed a steady growth since September. In 2011, the aerosol loading of the stratosphere was more intense and longer-term. For instance, the height of the extension of the aerosol component reached 40 km in January-March, and the aerosol was absent in the stratosphere within three months (May-July).
