Abstract
In 2010 and first half of 2011, a background aerosol content was observed in the atmosphere of the Northern Hemisphere midlatitudes. The report presents the observations of aerosol disturbances of the stratosphere in the second half of 2011, which were performed at lidar network stations of CIS countries CIS-LiNet in Minsk (53.9°N; 27.6°E), Tomsk (56.5°N; 85.0°E), and Vladivostok (43.0°N; 131.9°E). Data of lidar measurements at the sensing wavelengths of 353, 355, and 532 nm indicate that increased aerosol content was observed since June – July almost until the end of 2011 in the lower stratosphere up to the altitudes ~ 18 km. A well-defined, temporally stable aerosol layer was observed until October 2011 in the altitude interval ~ (13-17) km. The trajectory analysis of air mass transport in the stratosphere according to NOAA HYSPLIT MODEL with employment of CALIPSO satellite data shows that the increased aerosol content observed was most likely due to transport of eruption products of Grimsvötn volcano (May 21, 2011, Iceland: 64.4°N; 17.3°W).
