The Solomon group uses the Whole Atmosphere Community Model, a state-of-art global chemistry climate model spanning the troposphere, stratosphere, mesosphere and lower thermosphere.  We contribute to understanding the chemistry and climate impacts of polar ozone depletion in collaboration with colleagues at NCAR and other institutions.

The Whole Atmosphere Community Climate Model (WACCM) models atmospheric chemistry over the globe. This simulation shows the evolution of the ozone hole over the South Pole side-by-side during the two periods of August 1 - September 15 for the years 2018 and 2019. The 2019 ozone hole was rather unusual, and was analyzed by atmospheric scientists using atmospheric models and satellite observations. The pressure level 50 hPa corresponds to about 18 km, or 60,000 feet above sea level. This animation was produced at NCAR/ACOM by Simone Tilmes and Carl Drews.
