NOAA Announces Significant Investment in Next Generation of Supercomputers

The Commerce Department's National Oceanic and Atmospheric Administration (NOAA) recently announced the next phase in the agency’s efforts to increase supercomputing capacity to provide more timely, accurate, reliable, and detailed forecasts. By October 2015, the capacity of each of NOAA’s two operational supercomputers will jump to 2.5 petaflops, for a total of 5 petaflops – a nearly tenfold increase from the current capacity.

Ahead of this upgrade, each of the two operational supercomputers will first more than triple their current capacity later this month (to at least 0.776 petaflops for a total capacity of 1.552 petaflops). With this larger capacity, NOAA’s National Weather Service in January will begin running an upgraded version of the Global Forecast System (GFS) with greater resolution that extends further out in time – the new GFS will increase resolution from 27km to 13km out to 10 days and 55km to 33km for 11 to 16 days. In addition, the Global Ensemble Forecast System (GEFS) will be upgraded by increasing the number of vertical levels from 42 to 64 and increasing the horizontal resolution from 55km to 27km out to eight days and 70km to 33km from days nine to 16.

Computing capacity upgrades scheduled for this month and later this year are part of ongoing computing and modeling upgrades that began in July 2013. NOAA’s National Weather Service has upgraded existing models – such as the Hurricane Weather Research and Forecasting model, which did exceptionally well this hurricane season, including for Hurricane Arthur which struck North Carolina. And NOAA’s National Weather Service has operationalized the widely acclaimed High-Resolution Rapid Refresh model, which delivers 15-hour numerical forecasts every hour of the day.

The increase in supercomputing capacity comes via a $44.5 million investment using NOAA's operational high performance computing contract with IBM, $25 million of which was provided through the Disaster Relief Appropriations Act of 2013 related to the consequences of Hurricane Sandy. Cray Inc., headquartered in Seattle, plans to serve as a subcontractor for IBM to provide the new systems to NOAA.

NOAA's mission is to understand and predict changes in the Earth's environment, from the depths of the ocean to the surface of the sun, and to conserve and manage our coastal and marine resources.
