In preparation for the planned five-year update to the DOE Atmospheric System Research (ASR) Program Science plan, the program conducted four workshops in 2015-2016 on topical challenges in atmospheric process research, including: Secondary Organic Aerosols, Marine Low Clouds, Absorbing Aerosols, and Convective Processes. At this Town Hall, DOE program managers and workshop chairs will lead discussion on the outcome of these workshops as well as challenges and opportunities for DOE-led progress in each of the topical areas.
