Response of Global Climate to the Antarctic Ozone Hole
The Ozone and Climate Project team and guest--meteorologists, oceanographers and climatologists from around the world--met in MIT's Edwin Gilliland Auditorium from June 7-8, 2016 for their third annual progress meeting. This NSF-supported project aims to understand the role of the Antarctic ozone hole and its importance in the global picture of climate change. The project team explores this through observations, theory and modeling of the ozone hole and its behavior.
