Abstract:

The results of stratospheric aerosol observations at lidar stations of Roshydromet after the explosive eruption of the Raikoke volcano (Kuril Islands, 48.29° N, 153.25° E) in June 2019 are presented. By using direct trajectory analysis and observational data of the Caliop satellite lidar the aerosol trace in the stratosphere is revealed from the volcano around the pole to Western Siberia within a month after the eruption. The lidar measurements of volcanic aerosol from the end of July 2019 at the Roshydromet lidar stations in Obninsk, Znamensk, Novosibirsk, and Petropavlovsk-Kamchatsky are presented. Volcanic aerosol was observed in the layer from 13 to 18 km. The integral backscattering coefficient in the layer varied from the maximum (0,8–1,6) × 10^-3 sr^-1 in August-September 2019 to (0,2–0,3) × 10^-3 sr^-1 by the end of the year.

Keywords:
