Earth and Environmental System Modeling


EARTH AND ENVIRONMENTAL SYSTEM MODELING is part of the U.S. Department of Energy’s Office of Biological and Environmental Research (BER) Earth and Environmental Systems Sciences Division (EESSD). 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.

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.
