Space Weather Aviation Forecasting on a Global Scale

by D. J. Knipp and Michael A. Hapgood 14 October 201913 October 2021

Under a new mandate, consortia of the world’s major space weather centers will disseminate new space-weather advisories for civil aviators representing a significant change-of-state for space weather.
