This bill, known as the "Weather Innovation for the Next Generation Act of 2025" or the "WING Act of 2025," mandates the Director of the National Weather Service, in coordination with the Assistant Administrator for Oceanic and Atmospheric Research, to establish a Research, Development, Test, and Evaluation Program. The primary goal of this program is to ensure the continued performance of weather radar detection and prediction capabilities despite physical obstructions in the line of sight of such radar. The program will involve partnering with various entities, including industry and academia, to identify and test existing technologies and research new solutions. Key activities of the program include investigating solutions such as signal processing algorithms, short-term forecasting algorithms to replace contaminated data, and the use of dual polarization characteristics to mitigate the effects of wind turbines. The Director is also required to prioritize consideration of specific technology-based mitigation solutions, including multifunction phased array radar and the utilization of data from private-sector meteorological towers. The program has a termination date of September 30, 2030, or one year after a final recommendation is submitted, and requires annual reports to Congress detailing its implementation and progress.
