Earth System Model Development and Analysis

Funding Agency:
Department of Energy

The DOE SC program in Biological and Environmental Research (BER) announces its interest in receiving research applications for Earth and Environmental Systems Modeling (EESM). The goal of the EESM portfolio within the BER program is to develop and demonstrate advanced modeling and simulation capabilities, in order to enhance the predictability of the Earth system over multiple temporal and spatial scales. The EESM vision is to provide the best possible information about the Earth’s evolving system: in addition to promoting understanding of the natural world, this knowledge could be used to inform planning for energy assets and infrastructures. This FOA solicits research applications to advance the fundamental understanding of dynamic, physical, and biogeochemical processes required to systematically develop and analyze results from Earth System Models. The FOA will support: 1) further development of the marine biogeochemical simulations in Energy Exascale Earth System Model (E3SM); 2) hierarchical modeling, simulations and analysis using E3SM and other Earth system models to enhance understanding of biogeochemical (terrestrial and marine), aerosol, cloud, and/or aerosol-cloud interactions and feedbacks; 3) novel methodologies and techniques for model initialization, coupled data assimilation.

BER supports fundamental, interdisciplinary research to achieve a predictive systems-level understanding of Earth, environmental and biological systems. In particular, BER seeks to develop advanced mathematical methods and computational models for systems ranging from molecular to global scales and an ability to connect large and diverse datasets with models, which in turn enables more holistic and robust predictions of complex system behavior. More information on the BER program is available at and-environmental-research or

This FOA focuses on supporting research within two components of BER’s EESM activities ( within the Earth and Environmental Systems Sciences Division (EESSD): Earth System Model Development (ESMD), and Regional and Global Modeling Analysis (RGMA). The ESMD component focuses primarily on further development of the Energy Exascale Earth System Model (E3SM), while the RGMA component focuses primarily on scientific analysis based on E3SM as well as other Earth system models. Together, these activities broadly focus on the development, evaluation, and use of regional and global integrated Earth system models, to understand the behaviors and interactions between Earth systems and energy-related activities. The EESSD Strategic Plan (available at: describes research priorities and scientific grand challenges supported by these modeling activities. Further descriptions of the ESMD and RGMA activities and the topical areas of the solicitation are included below. The three specific topical areas of the FOA are described after the ESMD and RGMA descriptions.
