NOAA announces significant investment in next generation of supercomputers

“NOAA is America’s environmental intelligence agency; we provide the information, data, and services communities need to become resilient to significant and severe weather, water, and climate events,” said Kathryn Sullivan, Ph.D., NOAA’s Administrator. “These supercomputing upgrades will significantly improve our ability to translate data into actionable information, which in turn will lead to more timely, accurate, and reliable forecasts.”

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.

“We continue to make significant, critical investments in our supercomputers and observational platforms,” said Louis Uccellini, Ph.D., director, NOAA’s National Weather Service. “By increasing our overall capacity, we’ll be able to process quadrillions of calculations per second that all feed into our forecasts and predictions. This boost in processing power is essential as we work to improve our numerical prediction models for more accurate and consistent forecasts required to build a Weather Ready Nation.”

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.

“We are excited to provide NOAA’s National Weather Service with advanced supercomputing capabilities for running operational weather forecasts with greater detail and precision,” said Peter Ungaro, president and CEO of Cray. “This investment to increase their supercomputing capacity will allow the National Weather Service to both augment current capabilities and run more advanced models. We are honored these forecasts will be prepared using Cray supercomputers.”

"As a valued provider to NOAA since 2000, IBM is proud to continue helping NOAA achieve its vital mission," said Anne Altman, General Manager, IBM Federal. "These capabilities enable NOAA experts and researchers to make forecasts that help inform and protect citizens. We are pleased to partner in NOAA's ongoing transformation."

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. Join us on Facebook, Twitter, Instagram and our other social media channels.
