The Coupling, Energetics, and Dynamics of Atmospheric Regions (CEDAR) program is sponsored by the National Science Foundation. Quoting from the NSF program announcement at link)

'CEDAR is a broad-based, community-initiated, upper atmospheric research program. The goal is to understand the behavior of atmospheric regions from the middle atmosphere upward through the thermosphere and ionosphere into the exosphere in terms of coupling, energetics, chemistry, and dynamics on regional and global scales. These processes are related to the sources of perturbations that propagate upward from the lower atmosphere as well as to solar radiation and particle inputs from above. The activities within this program combine observations, theory and modeling.'

The program holds an annual competition for awards (deadline typically in May). It also sponsors the annual Workshop, typically held in late June, which brings together NSF program managers, leading researchers in the U.S., students, and visitors from abroad. The next two workshops will be held in Seattle, WA, June 22-27, 2014 and June 21-26, 2015.
