Technology boost: Earth System Modeling and Regional and Global Climate Modeling programs fund university research to maximize computer architectures for enhanced climate models


University awards were recently provided to applicants for the Scientific Discovery through Advanced Computing, or SciDAC, program solicitation, from BER's climate modeling programs to support collaborative research that will enhance spatial resolution, physical process representation, validation, and uncertainty quantification of climate models underpinned by high-performance petascale computing. The goal is to actualize and further foster direct collaboration between computational scientists and climate model developers to facilitate advances in climate modeling simulations.

About Earth System Modeling

Optimizing emerging high-performance computing and information technologies, the Earth System Modeling (ESM) Program concentrates on advancing coupled climate and Earth system models for climate change projections at global-to-regional spatial scales and temporal scales spanning decadal to centennial. The ESM program focuses on research that improves representations in specific model components to achieve credible high-resolution climate simulations that address the variability and predictability of climate system changes and directly impact societal issues pertaining to future energy use and technology. ESM research and modeling tools directly support the Regional and Global Climate Modeling (RGCM) program.

About Regional and Global Climate Modeling

The Regional and Global Climate Modeling (RGCM) program couples climate and Earth system models, focusing on regional and global climate change projections and temporal scales spanning decadal to centennial, to provide critical details about uncertainty and future variability of Earth's climate system. RGCM sponsors scientific projects that analyze multi-model climate change projections with the goal of quantifying uncertainties and feedbacks in Earth system processes, assessing climate sensitivity and variability, detecting and characterizing climate change (including examining regional contributions and model biases), and producing reliable projections.

In addition, both RGCM and ESM contribute to the Climate Variability and Change element of the U.S. Global Change Research Program (USGCRP) and coordinate with climate modeling programs sourced at other federal agencies, including, the National Science Foundation (NSF), National Oceanic and Atmospheric Administration (NOAA), and National Aeronautics and Space Administration (NASA).
