Radio frequencies are widely used in the timely measurement, collection and dissemination of critical foundational data including data from satellites, weather radar, surface observations, radiosondes etc. High quality weather and hydrologic forecasts and warnings required to ensure safety and enhance the nation’s economy are underpinned by these observations. At the same time, there is increasing and accelerating pressure from policymakers to optimize the use of the radio spectrum to support our increasingly connected world, resulting in the potential for radio frequencies used by our community to be no longer available or exhibit significant interference, affecting our community’s ability to perform our critical missions. This Town Hall will explore the current status of this issue from across the weather, water and climate enterprise, with a focus on the most pressing concerns. Additionally, opportunities to work together to meet the challenges and opportunities presented by this issue will be discussed.
