NASA Supercomputer Generates Closer Look at Future Climate Conditions in U.S.

Global models of the climate system are now the foundation for many important climate studies, but they typically show climate changes at very large geographic scales on the order of 100 to 250 kilometers. Using previously published large-scale climate model projections, a team of scientists from NASA has recently released monthly climate projections for the United States at a scale of one half mile (800 meters), or approximately the size of a neighborhood.
These new high-resolution climate projections provide a view of future U.S. temperature and precipitation patterns based on four different greenhouse gas
- Production of this dataset required hundreds of thousands of supercomputing hours and very large volumes of data. Previously, it would have taken more than a year to complete. Using the supercomputing resources provided by the NASA Earth Exchange (NEX) and the NASA Advanced Supercomputing facility at Ames, the team of scientists was able to produce the downscaled, high resolution climate dataset for the U.S. within months of release of the final global climate scenarios prepared for the next IPCC assessment report.
The new climate projections will help make it easier for resource managers and city planners to quantify anticipated
Researchers anticipate these new images will serve as an important resource for regional analyses of climate change that are being conducted by scientists at a variety of institutions, including the U.S. Dept. of Interior Climate Science Centers and the National Park Service.
"Climate changes threaten the integrity of parks throughout the National Parks system, and park mangers desperately need data at management-relevant scales to inform decisions,” said John Gross and William Monahan, ecologists with the National Park Service who are leading studies of climate change in our national parks. “These high-resolution assessments are the basis for implementing effective climate
