The National Weather Service (NWS) is conducting market research to assess capabilities for modernizing and supporting the Cooperative Observer Program (COOP), which involves approximately 6,700 surface observation sites. The NWS is evaluating three management models: Government-Owned/Government-Operated, Government-Owned/Contractor-Operated, and Contractor-Owned/Contractor-Operated (Data-as-a-Service). This is a Sources Sought Notice only, not a solicitation for proposals, bids, or quotes. No contract will be awarded from this notice, and the government will not pay for any submitted information. Performance location is across the distributed observation sites, but no specific timelines or budget amounts are provided.
