There are only four lidar stations in the world role of both tropical and northern volcanic eruptions in vol- which have almost continuously performed observations of canogenic aerosol loading of the midlatitude stratosphere is the stratospheric aerosol layer (SAL) state over the last also discussed. In addition to volcanoes, we considered other 30 years. The longest time series of the SAL lidar mea- possible causes of the SAL perturbations over Tomsk, i.e., surements have been accumulated at the Mauna Loa Obser- the polar stratospheric cloud (PSC) events and smoke plumes vatory (Hawaii) since 1973, the NASA Langley Research from strong forest fires.
