An Integration and Evaluation Framework for ESPC Coupled Models
Abstract
To realize its potential, a U.S. Earth system modeling and prediction capability must encompass a network of agencies and organizations that contribute model components, infrastructure, and scientific and technical expertise. The model component contributions must be integrated using coupling software, the coupled systems optimized for emerging computing platforms, and the predictive skill of the resulting models assessed using standard metrics. We propose to expand on our earlier integrative functions for the Earth System Prediction Capability (ESPC), using as a suite of Navy models (e.g., NavGEM, HYCOM) and the Community Earth System Model (CESM) in a set of component model swap experiments that are specifically designed to assess model fidelity, understand the impact of structural differences on weather and climate variability, and computational performance. The proposed activity described here outlines: (i) how we will expand on many of the code development/enhancement activities during the first three years of funding and (ii) how those technical developments will be tested in controlled science experiments that have direct application to predictive capability and further our understanding how differences in component model capabilities affect weather and climate variability and predictability. Previous work has laid the foundation for a Coupling Testbed as a resource available to ESPC modelers, with Testbed leads who have developed infrastructure for major modeling systems and can engage and motivate interactions with modelers at the National Aeronautics and Space Administration (NASA), the National Oceanic and Atmospheric Administration (NOAA), and other centers. As part of the proposed extension, the Testbed will be used to explore and prototype design and performance challenges related to integration, migrate optimizations to ESPC codes, and advance convergence of coupling interfaces to support knowledge transfer and controlled experimentation. This Coupling Testbed provides the ideal platform for the proposed component model swap experiments. Also as part of the proposed extension, we will work to broaden existing multi-agency computational working groups to address ESPC performance concerns and new application requirements.
