EARTH AND ENVIRONMENTAL SYSTEM MODELING is part of the U.S. Department of Energy’s Office of Biological and Environmental Research (BER) Climate and Environmental Sciences Division (CESD). Our focus is on the development, evaluation, and use of regional and global integrated Earth system models, to understand the interactions between climate and energy-related activities, and to inform adaptation to shifts in climate and societal requirements.

Cristiana Stan recently joined the U.S. Department of Energy’s (DOE) Earth and Environmental System Modeling (EESM) program under an Intergovernmental Personnel Act (IPA) assignment. In her new EESM role, Stan—an associate professor at George Mason University in Fairfax, Virginia—will work across EESM program areas, particularly in advancing novel scientific concepts and...
The U.S. Department of Energy (DOE) recently announced the selection of 76 scientists from across the nation to receive funding for research as part of the DOE Office of Science’s Early Career Research Program. Four awardees plan research projects connected to Earth and Environmental Systems Sciences (EESM). They include: Matthew Hoffman, Los Alamos National Laboratory...
Did you know the Energy Exascale Earth System Model (E3SM) project has a dedicated website at Check it out for detailed news and information on events, collaboration, research areas, data, publications, technical highlights, software, documentation, career opportunities, and more. You can also subscribe to the E3SM newsletter, “Floating Points,” by...
In this feature story published by the DOE Office of Science, discover how EESM-supported research is advancing the understanding of atmospheric rivers—large sections of the atmosphere full of water vapor—in water and climate cycles. An atmospheric river drove this storm over California’s Russian River. Every time this river flooded between 2004 and 2014, it was because...
How can scientists collaborate to analyze and compare petabytes of data from all around the world on a short deadline? AGU’s Eos featured a story, “Hackathon Speeds Progress Toward Climate Model Collaboration,” by Regional and Global Model Analysis (RGMA) program area scientists Wilbert Weijer of Los Alamos National Laboratory, Forrest Hoffman of Oak Ridge National...

Program Information

Earth System Model Development

The Earth System Model Development (ESMD) program area supports innovative and computationally advanced earth system modeling capabilities, with the goal of providing accurate representations of the fully coupled and integrated Earth system, as needed for energy and related sectoral infrastructure planning.

Regional & Global Model Analysis

The Regional & Global Model Analysis (RGMA) program area advances the predictive understanding of Earth’s climate by focusing on a scientific analysis of the dominant sets of governing processes that describe climate change on regional scales.

MultiSector Dynamics

The MultiSector Dynamics program area seeks to advance scientific understanding of the complex interactions, interdependencies, and co-evolutionary pathways of human and natural systems, including interdependencies among sectors and infrastructures. These model efforts inform some of the most significant energy, economic, and infrastructure decisions affecting the world today.
