The National Oceanic and Atmospheric Administration (NOAA) introduced three space weather scales (SWS) in 1999 as a way to communicate current and future space weather conditions, and their possible effects on people and systems, to the public. IDA’s Science and Technology Policy Institute (STPI) assisted NOAA in the revision and eventual deployment of the revised SWS, which are currently used worldwide to initiate hazard preparedness and mitigation operations. STPI engaged multiple stakeholders to identify user needs and interests, and to ensure that their views are incorporated into any revisions.
