Radio frequency spectrum is crucial to the operation of critical technologies to weather forecasting and other Earth predictive capabilities. More demand for spectrum and greater interference in critical bands requires the weather enterprise to monitor its current and future needs for spectrum. This requires monitoring both international and domestic regulatory proceedings and being prepared to take action by effectively communicating the value of weather predictions and submitting regulatory comments.

Over four weeks at the end of 2023, the International Telecommunications Union (ITU) convened the World Radiocommunication Conference (WRC-23) in Dubai to review and revise the international treaty governing the use of radio-frequency spectrum across the globe. Weather enterprise representatives were present at those sessions as there were important discussions that could impact space weather prediction. There were also important dialogues on planning for future agenda items at the next WRC in 2027 related to spectrum near 52 GHz, which are crucial bands for satellite meteorology and numerical weather prediction.

The panelists in this session from NOAA, the WMO and other agencies will speak to the developments on spectrum related to space weather and microwave sensor measurements that are critical to numerical weather prediction. There will be ample opportunities for questions and audience participation in this annual dialogue on spectrum at the AMS Annual Meeting.
