August 19, 2024 - The Radar Operations Center completed a $150 million, nine-year Service Life Extension Program (SLEP) that extends the lifespan of the 159 weather radars that make up the nation's Next Generation Weather Radar network (NEXRAD). The NEXRAD radar is a vital tool used by National Weather Service forecasters to warn their communities of severe and hazardous weather and ultimately save lives and property.
With the refurbishment of the radar pedestal in Missoula, Montana, earlier this month, all 122 National Weather Service NEXRAD systems have been fully upgraded. Additionally, 37 NEXRAD systems owned and maintained by the Federal Aviation Administration and the Department of Defense have also been upgraded, completing the upgrade of the entire weather radar network.
"We have improved our radar network by eliminating obsolete items while investing in new technology," said Terry Clark, Radar Operations Center Director. "We are already seeing the positive results of this project in reduced life-cycle costs due to less maintenance needs. An added bonus is that we are maintaining radar availability at a high level after trending down prior to the upgrades, and the number of parts needing to be replaced has decreased by approximately 50 percent since 2018."
Technicians repaired and refurbished major components to extend the operability of the radars beyond 2035 in a project that was completed on time and under budget. The Service Life Extension Program included five major upgrades:
NEXRAD technology was developed in the 1980s and built in the 1990s. While incremental upgrades and modernization have occurred in the last 20 years, this SLEP effort addressed the major components that had not been updated, were obsolete, or required additional refresh of technology. These SLEP upgrades will ensure the radar's reliability, maintainability, and availability into the next decade.
To ensure the reliability of weather radar technology beyond the next decade, NOAA is developing requirements for Radar Next. This program will identify and deploy the next generation of radar coverage to improve public safety, enhance disaster preparedness, and advance scientific research and climate studies.
