What Does PSC Stand For?
PSC stands for Polar Stratospheric Cloud
Polar Stratospheric Clouds (PSCs) are ice and nitric acid-containing clouds that form in the polar stratosphere under extremely cold conditions, typically during winter. These clouds play a crucial role in stratospheric chemistry, particularly in the depletion of ozone. PSCs provide a surface for the chemical reactions that lead to the breakdown of ozone-depleting substances, significantly impacting the ozone layer and influencing climate patterns in polar regions. Their presence is an important feature of the atmospheric environment at high latitudes.
