The Improving Flood and Agricultural Forecasts Act of 2025 directs the Under Secretary of Commerce for Oceans and Atmosphere to maintain and expand the National Mesonet Program. The goal is to improve observations for atmospheric, drought, fire, and water events by leveraging non-Federal data sources and strengthening coordination across the weather enterprise in the United States.
The act also sets out program elements, governance structures, and funding that would support broader networks of environmental sensors and better integration with satellite data to improve forecasts and warnings.
At a Glance
What It Does
The bill requires the Under Secretary to maintain the National Mesonet Program, expand environmental observations, and coordinate with satellite data and external networks through memoranda of understanding.
Who It Affects
NOAA and the Weather Enterprise, state and local governments, universities, private mesonet operators, and emergency management agencies.
Why It Matters
Expands data density and collaboration to improve hyperlocal forecasts, drought monitoring, and flood responses, with a focus on regions currently underserved by existing networks.

What This Bill Actually Does
The bill charges the Under Secretary of Commerce for Oceans and Atmosphere with maintaining the National Mesonet Program and pushing to increase the density and variety of environmental observations. It emphasizes incorporating data from non-Federal networks—such as local monitoring stations and soil moisture sensors—and coordinating with satellite data to support weather prediction, warnings, and emergency response.
The program aims to improve baseline forecasts and hyperlocal skill, which should help protect agriculture, infrastructure, and public safety.
The Five Things You Need to Know
Not less than 15% of the Program’s annual appropriation must be used to fund financial assistance for State, Tribal, private, and academic mesonet initiatives.
The program expands observation density to include soil moisture data, road weather, and additional in situ sensors to support forecasts and emergency management.
The Under Secretary may establish memoranda of understanding with external data networks and must coordinate with satellite data and services.
An advisory committee with academic input will guide data needs, partnerships, and data expansion.
Regular briefings to Congress are required through 2035 to report on implementation, funding, and data gaps.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
National Mesonet Program—establishment and purpose
This section mandates that the Under Secretary maintain the National Mesonet Program and outlines its core purposes: to improve understanding of and forecasting for atmospheric, drought, fire, and water events by leveraging non-Federal environmental data. It emphasizes cross-sector coordination among private, public, and academic weather actors to strengthen the Weather Enterprise in the United States.
Program elements—data density and networks
The section details mechanisms to increase data density, including better quantity and density of observations used by NOAA and the National Weather Service, the inclusion of soil moisture data, groundwater profiling, and road-weather observations. It also envisions incorporating new terrestrial and marine data sources and improving predictive models to support rapid warnings.
Financial and technical assistance
This provision authorizes not less than 15 percent of annual program funding for financial assistance to State, Tribal, private, and academic entities to build or upgrade mesonet capacity. It sets terms for data sharing, data quality, and maintenance obligations, and allows coordination with other Federal funding where appropriate.
Advisory Committee
An active advisory committee, potentially drawn from existing Federal experts or subcommittees, will guide data needs, acquisitions, and partnerships. It must include academic expertise to help identify collaborations and regional data expansion opportunities.
Regular briefings
The Under Secretary is required to provide annual briefings to relevant Congressional committees on program activities, funding, data-sharing efforts, adherence to recommendations from the advisory committee, and progress toward closing data gaps.
Appropriations authorization
The act specifies a ceiling for annual funding through 2029 to support the Program within the National Weather Service, with increasing appropriations to enable expanded data collection and network integration.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- NOAA/NWS benefits from richer, higher-resolution data to improve forecast accuracy and warning timeliness.
- State and Tribal governments gain enhanced local forecasting, emergency planning, and potential access to grant funding for mesonet expansion.
- Private sector weather data providers and mesonet operators can participate in funded expansion and data-sharing arrangements.
- Universities and research institutions gain broader access to mesonet data for scientific studies and collaboration.
- Agricultural producers and food security agencies improve drought and soil moisture monitoring to support planning and risk management.
Who Bears the Cost
- Federal government bears ongoing program management and data integration costs.
- Recipient entities (States, Tribes, private sector, and academic institutions) must contribute non-Federal funds, provide data, and maintain their infrastructure for at least 5 years.
- Local and regional agencies may incur maintenance costs to operate new or expanded monitoring stations.
- Private sector data providers might need to invest in data standardization and interconnection with Federal systems.
Key Issues
The Core Tension
Expanding observation networks and data sharing can improve forecasts and emergency response, but it requires predictable funding and strong data governance to ensure data quality and interoperability across diverse partners.
The bill’s expansion of the mesonet program hinges on sustained funding and robust data-sharing agreements. A key tension is balancing the desire for broader, higher-density observations with the need to manage costs, ensure data quality, and maintain interoperability with existing Federal data systems.
While the act opens doors to non-Federal participation, it also imposes obligations for data provision, maintenance, and adherence to standards that could create operational friction for some partners. Moreover, aligning multiple networks—federal, state, academic, and private—requires careful governance to avoid fragmentation or duplication of effort.
