Center for Atmosphere-Ocean Science

The Center for Atmosphere Ocean Science is a unit of the Department of Mathematics, within the Courant Institute of Mathematical Sciences.  Our mission is to advance our understanding of and ability to predict the coupled atmosphere, ocean and ice system through the use of mathematical and computational tools and analysis of observations; and to train the next generation of leading theoretical and computational climate scientists to face one of the most consequential problems of the 21st century.

Diversity, Equity & Inclusion: The Center for Atmosphere Ocean Science comprises students, postdocs and faculty. Our program values equity, diversity and inclusion as essential elements of an effective, safe and ethical research and educational environment.   It is our responsibility to remove barriers to knowledge and resources that limit access for marginalized groups;  to create a safe, respectful, and inclusive environment for all our members and the communities with which we interact; and to continually evaluate ourselves, our program, and our educational and research outcomes to ensure we live up to these standards.
