Coupling, Energetics, and Dynamics of Atmospheric Regions (CEDAR)

Funding Agency:
National Science Foundation

The Coupling, Energetics, and Dynamics of Atmospheric Regions (CEDAR) program is a broad-based research program with the goal of understanding 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 include observations from ground-based and space-based platforms, theory, and modeling.

Eligibility Requirements

Limit on Number of Proposals per PI or Co-PI: 2. Only two research proposals per investigator, either as a PI, co-PI, or in a subaward, are allowed per target date in the CEDAR Program.



Amount Description

Estimated program budget, number of awards and average award size/duration are subject to the availability of funds. Normally, CEDAR awards are made for a duration of three years, but proposers may request from one to five years of funding provided the requested duration is adequately justified. NSF estimates making 10 to 15 grant awards. The typical award size is approximately $150,000 per year. The anticipated annual funding amount for new awards is $3,000,000 pending availability of funds.
