NASA Center for Climate Simulation

NASA Center for Climate Simulation. The NASA Center for Climate Simulation (NCCS) is a high-performance computing facility dedicated to advancing the understanding of Earth's climate system. Established in 2010 and located at the Goddard Space Flight Center in Maryland, it provides the computational power and data services essential for running sophisticated climate and weather models. The center supports the research goals of the NASA Earth Science Division and collaborates with scientists across the United States and internationally to project future climate scenarios and analyze vast datasets from satellite observations.

Overview and Mission

The primary mission of the facility is to provide the advanced computational capabilities required for state-of-the-art modeling and analysis of the global climate system. It serves as a centralized resource for NASA scientists and their collaborators, enabling research that integrates observations from missions like those of the Earth Observing System with complex simulation models. The center's work is critical for improving the predictive accuracy of climate models, which inform assessments by bodies such as the Intergovernmental Panel on Climate Change. By managing and processing petabytes of data from instruments on satellites like Terra and Aqua, the NCCS plays a pivotal role in transforming raw data into actionable scientific knowledge about planetary changes.

Computational Resources and Infrastructure

At the core of the NCCS is its collection of powerful supercomputers, which have included systems like the Discover cluster featuring processors from Intel and AMD. This infrastructure provides hundreds of petaflops of computing power, housed within a high-efficiency data center at the Goddard Space Flight Center. The center utilizes sophisticated data storage systems, such as the High-Performance Storage System, to manage the immense volume of model output and observational data. To ensure efficient scientific workflows, the NCCS also supports a variety of software environments and visualization tools, allowing researchers to analyze complex simulations of atmospheric chemistry, ocean circulation, and ice sheet dynamics.

Key Research and Modeling Projects

The center hosts and supports execution of some of the most advanced global climate models, including the Goddard Institute for Space Studies Model E and the GEOS-5 model developed by the Global Modeling and Assimilation Office. These models are used for major projects like the Climate Model Intercomparison Project, which feeds into the Intergovernmental Panel on Climate Change assessment reports. Research initiatives often focus on decadal-scale climate predictions, detailed simulations of extreme weather events such as Hurricane Sandy, and the study of critical components like the Atlantic meridional overturning circulation. The NCCS also enables high-resolution modeling to understand urban heat islands and the impacts of aerosols on regional climate patterns.

Data Services and Public Access

A fundamental service of the NCCS is providing access to massive climate datasets for the broader research community and the public. It operates the NASA Earth Exchange, a collaborative platform where scientists can share data, tools, and analysis results. Key datasets, including outputs from the Modern-Era Retrospective analysis for Research and Applications and the North American Land Data Assimilation System, are archived and distributed through the center. Many of these resources are made available via portals aligned with NASA's open data policies, supporting educational work at institutions like the University Corporation for Atmospheric Research and informing policy development.

Collaborations and Partnerships

The NCCS engages in extensive collaborations with other U.S. agencies, including the National Oceanic and Atmospheric Administration, the United States Department of Energy, and the National Science Foundation. It is a key participant in interagency efforts like the U.S. Global Change Research Program. Internationally, the center partners with organizations such as the European Centre for Medium-Range Weather Forecasts and contributes to global initiatives like the Coupled Model Intercomparison Project. These partnerships are essential for model development, data sharing, and addressing grand challenge questions in climate science, often involving academic researchers from universities like the Massachusetts Institute of Technology and the University of California.
