DOE’s E3SM is a new high-resolution coupled Earth system model, designed to address energy-related science challenges and to effectively use DOE high performance computers. E3SM has released version 1 (model, data and analysis tools) and opened its github code repository. At this Town Hall we will share model results and computational performance from a range of atmospheric model configurations and resolutions. Science and development plans for the project, with focus on the atmosphere will also be presented. Several new atmospheric physics directions are under consideration by the project, as well as a longer term effort to run at cloud-resolving scales and use DOE exascale computers. Opportunities to engage with the E3SM project will be presented. DOE sponsors and project leaders will address questions and invite feedback from the audience. (See also: https:://E3SM.org)
