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.

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...
Researchers studied why the latest climate models indicate that the planet’s equilibrium climate sensitivity is greater than previous generations of models have predicted.

Why is the response of the global average surface temperature to a doubling of carbon dioxide greater than what previous generations of models have...
Xujing Davis has joined the U.S. Department of Energy (DOE) as program manager for the Earth System Model Development (ESMD) component of the Earth and Environmental System Modeling Program (EESM).   In her new role, Dr. Davis is responsible for the development and demonstration of the Energy Exascale Earth System Model (E3SM) and related research. Along with Regional...
Congratulations to Stephen A. Klein of Lawrence Livermore National Laboratory (LLNL). He was recently appointed a Fellow of the American Meteorological Society (AMS) at the 2020 AMS Annual Meeting in January. “I am grateful to my colleagues for the recognition of my contributions to the field,” says Klein, who was honored with 26 other AMS members as 2020 Fellows.  Much...

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.
