“…To identify the source of aerosol formations, recorded in the atmosphere over Tomsk and Surgut, back trajectories of air masses were constructed. The technique for constructing direct and back trajectories of air masses is widely used for identification of sources of anomalous atmospheric formations (e.g., [2,16]). The trajectories presented show that aerosol cloud formations recorded in the atmosphere over Tomsk and Surgut were brought from the region of primary localization of ejecta of Eyjafjallajökull volcano and reached the lidar observation sites in corresponding periods of time.…”

We present the results of lidar measurements of the vertical distribution of optical parameters of anomalous aerosol formations in the atmosphere and the polarization state of backscattered sounding radia tion, obtained in Tomsk (56.48°N; 85.05°E) and Surgut (61.25°N; 73.43°E) in April -May 2010. Data from measurements using back trajectory analysis of atmospheric air mass transport according to the NOAA HYSPLIT MODEL showed that the observed anomalous aerosol formations were due to transport of the products of the Eyjafjallajökull volcano eruption in Iceland (April 14, 2010). First traces of the volcanic erup tion were recorded in the troposphere over Tomsk on April 19. The volcanic aerosol persisted in the tropo sphere for about 10 days in total; it penetrated into the stratosphere insignificantly and could not have notice able long term radiation and thermal effects.

“…After eruptions of Okmok and Kasatochi volcanoes, the aerosol disturbance of the stratosphere was observed at the observation sites in Minsk (53.9 • N; 27.4 • E), Tomsk, and Vladivostok (43.0 • N; 131.9 • E) at lidar network CIS-LiNet for monitoring aerosol and ozone in CIS regions until late 2008. The results of these measurements, as well as the results of expedition measurements, performed by Institute of Atmospheric Optics in Gobi Desert, were considered in detail in [13], together with the air mass trajectory analysis.…”

The lidar measurements (Tomsk:56.5∘N;85.0∘E) of the optical characteristics of the stratospheric aerosol layer (SAL) in the volcanic activity period 2006–2011 are summarized and analyzed. The background SAL state with minimum aerosol content, observed since 1997 under the conditions of long-term volcanically quiet period, was interrupted in October 2006 by series of explosive eruptions of volcanoes of Pacific Ring of Fire: Rabaul (October 2006, New Guinea); Okmok and Kasatochi (July-August 2008, Aleutian Islands); Redoubt (March-April 2009, Alaska); Sarychev Peak (June 2009, Kuril Islands); Grimsvötn (May 2011, Iceland). A short-term and minor disturbance of the lower stratosphere was also observed in April 2010 after eruption of the Icelandic volcano Eyjafjallajokull. The developed regional empirical model of the vertical distribution of background SAL optical characteristics was used to identify the periods of elevated stratospheric aerosol content after each of the volcanic eruptions. Trends of variations in the total ozone content are also considered.

“…The 2010 average relative discrepancy between the ground based and satellite data, retrieved with the OMI-DOAS algorithm, is 3.8 DU (1.1% of the annual average). As an illustration, Figure 1b and Sarychev Peak) had relatively low intensity (almost two orders of magnitude less intense than Pinatubo volcano, by the mass of sulfur dioxide injected to the stratosphere) and was accompanied by short term (within a few months) increases in SA con tent [17,19]. Simultaneously, minor short term TO changes were observed.…”

The paper compares the results of ground based measurements of the total ozone (TO) content in Tomsk (56.48°N, 85.05°E) using the M 124 ozonometer, with satellite data obtained with the help of TOMS instruments. Different algorithms of TO retrieval from satellite data are considered. The TO trends over Tomsk, and at some northern hemisphere sites, for the period of 1979-2010 are analyzed. Based on the sat ellite and ground based measurements for Tomsk, there is a negative linear trend of (-2.3 ± 0.1) DU per year for the period of 1979-1995 and a positive trend of (1.08 ± 0.1) DU per year for the period of 1996-2010.
