As noted by policy letters and statement, radio spectrum is integral to many aspects of meteorology, essential to the operation of radars, satellites, passive and active remote sensing, and dissemination. Domestic and international regulators are constantly looking for new spectrum in support of commercial wireless. Some proposals can impact spectrum usage for meteorology and hydrology. The community must better understand the role of radio spectrum in the creation and transmission of scientific data, products, forecasts, advisories, and warnings.
