The Radar Operations Center (ROC) with the National Weather Service (NWS) recently completed a $150 million, nine-year project called SLEP. SLEP stands for Service Life Extension Program, which aims to extend the lifespan of the 159 weather radars that make up the nation’s Next Generation Weather Radar network (NEXRAD). 122 NEXRAD radars are owned by the NWS, with 37 additional radars owned by the FAA and DoD, but all have been upgraded.
The director of the ROC says the program worked to eliminate obsolete items, while also investing in new technology. They’ve already begun seeing positive results in reduced life-cycle costs and less maintenance. The repaired and refurbished components should extend the life of the radars beyond 2035.
Five major upgrades were completed during the project, including a refresh of the digital signal processor, refresh of the transmitter, refurbishment of the pedestal, refurbishment of the equipment shelter, and new generators.
Now that the project is complete, the updated radars will be a better tool to forecasters and help them warn their communities of severe and hazardous weather, and ultimately save lives and property.
