Mission

The mission of the Atmospheric Physics, Chemistry and Climate group is to develop and employ computer models -- alongside a wide range of atmospheric chemical and meteorological measurements -- to advance our understanding of the earth's past, present, and future atmospheric climate and composition.

Research Highlights

Study by John Austin and colleagues on the ozone recovery date

The figure shows the stratospheric ozone recovery date as a function of latitude for a baseline column ozone level simulated on a particular year given on the abscissa. The results were obtained from a range of coupled chemistry climate models (including the GFDL model AMTRAC3) which contributed to the Chemistry Climate Model Validation (CCMVal) project. Ozone recovery is anticipated over about half of the Earth's surface. (more)
