Ecosystem Projects

The E3SM project does not exist in isolation, but rather as part of an international effort in Earth system science research. The connections primarily are through complementary, and in many cases coordinated, efforts funded by the DOE Office of Science. The most relevant connections are provided here explicitly, but with an understanding that there are many more, and equally important, semi-formal and informal collaborative activities.

E3SM is the center of a research Ecosystem of closely related and interdependent projects supported by the DOE Office of Science. Essential to E3SM and an essential part of its ecosystem is the Scientific Discovery through Advanced Computing (SciDAC) partnership between BER and the Office of Advanced Scientific Computing Research (ASCR) to dramatically accelerate progress in scientific computing, including Earth system modeling. The Goal of the Exascale Computing Project’s (ECP) Application Development focus area is to deliver a broad array of comprehensive science-based computational applications that effectively utilize exascale HPC technology to provide breakthrough simulation and data analytic solutions for scientific discovery, energy assurance, economic competitiveness, health enhancement, and national security. A version of the E3SM model that employs superparameterization was selected as one of the applications.

Additionally, within BER several new projects with close connections to E3SM were recently initiated. These include two projects that integrate across the BER Earth and Environmental Systems Modeling (EESM) programs to improve coastal modeling of the Arctic and mid-Atlantic regions; a project focusing on improved treatment of aerosol-cloud interactions at convection-permitting scales, and two projects supported by the BER Data Management program that focus on visualization of E3SM simulations.

Additional BER-Supported Partnerships

The E3SM project is part of the BER Earth System Model Development (ESMD) Program. ESMD supports the development of all essential components of the coupled Earth-human system needed to simulate Earth system and climate by DOE’s research community. ESMD closely collaborates with the Regional and Global Model Analysis (RGMA) Program with ESMD primarily supporting model development while RGMA focuses on model analysis, intercomparison, metrics and validation, as well as using the models to evaluate system sensitivities and feedbacks. For global atmospheric model development, ESMD partners with BER’s Atmospheric System Research (ASR) Program to improve cloud and aerosol parameterizations needed to understand how clouds are shifting and influencing climate sensitivity. For land modeling, ESMD collaborates with BER’s Terrestrial Ecosystem Science (TES) Program to incorporate new modeling capabilities that are based on TES field investigations within particular regions. ESMD and the MultiSector Dynamics (MSD) Program collaborate on the development of coupled human-natural systems, such as understanding how land and water management activities affect the Earth system, as needed for optimal detailed Earth system simulations.

Since E3SM will be producing very-high resolution, and high frequency (sub-daily) model output, workflows to manage (download, move, store and analyze) large model outputs are needed. ESMD collaborates with BER’s Data Management (DM) on the infrastructure and tools needed for managing large model output datasets. The Earth System Grid Federation (ESGF), supported by DM, is critical for hosting and sharing the data generated by E3SM and other climate models.
