Space weather aviation forecasting on a global scale

By Smead Aerospace Research Professor Delores Knipp and RAL Space Head of Space Weather Michael Hapgood:

On November 7, 2019, in response to an International Civil Aviation Organization (ICAO) mandate, the world’s major space weather centers will start issuing global advisories related to disruptions in: high-frequency radio communications; communications via satellite; Global Navigation Satellite System (GNSS)-based navigation and precision location; and enhanced radiation risk to aircraft occupants.

As indicated by the “I” in ICAO, these new forecasting efforts transcend national boundaries. Primary responsibility for the global-24/7, watch, and advisory duties will rotate bi-weekly among the space weather centers.

In a real sense this represents a ‘change-of-state’ for the space weather discipline, thus aligning the discipline with expectations from the meteorology community. While space weather has been part of military aviation mission-planning for some time, civil aviators have not had consistent, world-wide access to space weather information.
