Stratospheric ozone depletion through catalytic chemistry involving man‐made
chlorofluorocarbons is an area of focus in the study of geophysics and one of the global …

Polar stratospheric clouds (PSCs) play important roles in stratospheric ozone depletion
during winter and spring at high latitudes (eg, the Antarctic ozone hole). PSC particles …

The physical state of a material is described as its phase. Common phases of the molecule
H2O include vapor, liquid water, and ice. Examples of these phases in the atmosphere are …

We evaluate polar ozone depletion chemistry using the specified dynamics version of the
Whole Atmosphere Community Climate Model for the year 2011. We find that total ozone …

▪ Abstract Liquid and solid particles in polar stratospheric clouds are of central importance
for the depletion of stratospheric ozone. Surface-catalyzed reactions on these particles, and …

There is extensive evidence to suggest that stratospheric aerosols can remain liquid to very
low stratospheric temperatures, despite being highly supercooled. Even polar stratospheric …

Calorimetric freezing experiments with aqueous sulfuric and nitric acid solutions are
presented and applied to the formation of polar stratospheric clouds (PSCs). We show that …

Chemical reactions on polar stratospheric cloud (PSC) particles are responsible for the
production of reactive chlorine species (chlorine 'activation') which cause ozone destruction …

This paper reviews experimental and theoretical work on the nonreactive uptake of acidic
trace gases such as HCl, HNO3, HBr, HONO, and SO2 on ice. The focus is on work …

Polar stratospheric clouds (PSCs) at 22–26 km were observed over the Norwegian
mountains by airborne lidar on January 15, 1995. Simulations using a mesoscale model …
