HamSCI was well represented at the Coupling, Energetics and Dynamics of Atmospheric Regions (CEDAR) Workshop, held 21-26 June in Des Moines, Iowa.

The NSF CEDAR Workshop provides the community an opportunity to self-organize, exchange and foster new ideas. It has a strong educational component.

The Workshop included community organized breakout workshops/sessions, poster sessions with a student poster competition, a student day, plenary sessions with science highlights, agency updates and tutorials, a distinguished lecture, and a prize lecture.
