September ozone hole has shrunk by 4 million square kilometers since 2000.
The Program in Atmospheres, Oceans, and Climate oversees a broad program of research and education directed at understanding the Earth in all its aspects - physical, chemical and biological - and how Earth has evolved over time to its present state and its likely future trajectory.
We make use of observations, theory and models and also place our studies in the context of planetary systems. Many of the most important discoveries in our science, such as chaos, the chemistry of the ozone hole and the physics of hurricanes were made by PAOC scientists.
