Pscs are polar static clouds
WebIce particles found within polar stratospheric clouds (PSCs) and upper tropospheric cirrus clouds can dramatically impact the chemistry and climate of the Earth's atmosphere. The formation of PSCs and the subsequent chemical reactions that occur on their surfaces are key components of the massive ozone hole observed each spring over Antarctica ... WebAlso called nacreous clouds, PSCs form in the lower stratosphere at altitudes between 15 and 25 km (about 50,000 to 80,000 feet), far above even the highest clouds in the …
