The stratosphere is typically very dry, and normally there are no clouds at all. However, under certain conditions, PSCs can form.

WebPolar Stratospheric Clouds (PSCs) contribute to catalytic ozone destruction by providing surfaces for the conversion of inert chlorine species into active forms and by denitrication of the stratosphere. WebPolar stratospheric clouds (PSCs) form seasonally over the polar regions. Satellite-based instruments have been monitoring these clouds long before the discovery of the ozone hole by observing the attenuation of sun light, which is scattered at wavelengths characteristic of the size of the cloud partic-les.
