Stratospheric aerosols are involved in cloud formation processes, especially in polar regions where thermodynamical conditions lead to polar stratospheric clouds (PSC) formation. Beside the well-known chemical effect of these clouds on polar ozone, the overall radiative impact of PSC and especially...
