During long-term measurements at the Siberian lidar station of the Institute of Atmospheric Optics SB RAS on February 5-6, 2025, pronounced aerosol layers were recorded in the stratosphere of Tomsk. Analysis of lidar and additional meteorological information showed that at that time, a rather rare phenomenon for mid-latitudes was observed - polar stratospheric clouds. These clouds, according to the data obtained, can be classified as type I clouds. The constructed reverse trajectories of air mass movement at the altitudes of formation of polar stratospheric clouds over Tomsk showed that anomalously cold air masses were brought from the polar regions of Norway and Greenland.
