We are a community studying the space-atmosphere interaction region.


Our Mission

CEDAR’s mission is to understand the fundamental properties of the space-atmosphere interaction region; identify the interconnected processes that define the local and global behavior, the evolution, and influence on the SunEarth system; and to explore their predictability.

The mission of CEDAR is continuously evolving to anticipate the next generation of scientific breakthroughs and foster cross-disciplinary activities by exploring connections between CEDAR science and other disciplines.
