The Department of Atmospheric and Oceanic Sciences (ATOC) at the University of Colorado at Boulder is located in a region having the greatest concentration of geophysical researchers in the nation and perhaps the world.  The proximity of ATOC to this atmospheric and oceanic science “ground zero” is the foundation of our unique philosophy and vision, which elevates our department to one of worldwide prominence.  The guiding principle of ATOC is to be the focal point for atmospheric and oceanic science education and research training in this geographic region of world-renown excellence.

The Department of Atmospheric and Oceanic Sciences (ATOC) is an interdisciplinary program that provides an educational and research environment to examine the dynamical, physical, and chemical processes that occur in the atmosphere and the ocean. A major theme is the establishment of a physical basis for understanding, observing, and modeling climate and global change.
