UNSPSC 81151503: Hydrometeorology

UNSPSC 81151503 Hydrometeorology is a Commodity code tracking state and local procurement of weather observation, forecasting, and related hydrometeorological services and equipment. Recent opportunities show a mix of automated weather observation systems (AWOS) hardware, real-time weather forecasting and alert services for transportation operations, and irrigation system improvements that incorporate weather-responsive controls. State and local buyers under this code include state transportation departments (Georgia DOT, Illinois DOT), municipalities (City of DeBary, Florida), and related operational agencies. Work ranges from establishing contracts with qualified suppliers for AWOS commodities to renewing multi-year weather forecasting service agreements that feed alert systems to highway maintenance forces and from engineering and installation of weather-integrated irrigation infrastructure in municipal parks. The issuing-body mix is dominated by state transportation departments and local public works entities.

Geographic activity centers on the Southeast and Midwest. Georgia Department of Transportation posted an eRFQ on April 8, 2026 (due May 4, 2026) to establish a contract for AWOS equipment and related commodities supporting transportation operations. Illinois Department of Transportation issued a renewal notice on March 4, 2026 (due March 19, 2026) for enhanced weather forecasting services covering IDOT Districts 1 through 9, with incumbent vendor DTN, LLC selected for continuation at $254,022.22 annually. The City of DeBary, Florida posted a competitive bid (Solicitation 0315) on April 13, 2026 for Rob Sullivan Park irrigation system improvements involving conversion to a Hunter automated system with weather-responsive controls; the project had an Engineer's estimate of $90,000 and a mandatory pre-bid conference on March 25, 2015. This code sees steady but narrow activity, concentrated among transportation agencies and municipalities managing weather-dependent infrastructure.
