About Space Weather Workshop

Space Weather Workshop is an annual gathering that brings together industry, academia, and government agencies for a dynamic exchange on space weather. What began in 1996 as a forum for the space weather user community has grown into the nation's premier event dedicated to all aspects of space weather.

This event explores the wide-ranging impacts of space weather on modern technology, with a program that highlights effects on communications, navigation, spacecraft operations, human space exploration, aviation, space traffic coordination, and electric power systems. Discussions will also focus on the most pressing needs for operational services, guiding future research and the development of new high-value capabilities for real-world applications. The workshop serves as a vital platform for fostering collaboration among researchers, space weather service providers, and end users.

Space Weather Workshop is organized by the University Corporation for Atmospheric Research (UCAR) Cooperative Programs for the Advancement of Earth System Science (CPAESS), along with a community-based organizing committee and co-sponsored by the NOAA Space Weather Prediction Center, the NSF Division of Atmospheric and Geospace Sciences, and the NASA Heliophysics Division. 

Prior Space Weather Workshops and associated presentations are available.
