The Upper Atmosphere Research Satellite helped scientists understand the energy input, chemistry and dynamics of the upper atmosphere and the interaction between the upper and lower atmosphere. Throughout its remarkable 14 year mission, UARS made observations that led to major scientific discoveries. UARS confirmed the role of chlorofluorocarbons (CFCs) in ozone depletion and clarified chemical processes that cause the Antarctic ozone hole.
