Data Mining Tool

All Forecast Regions
Effective November 7, 2019, the NWS Space Weather Prediction Center (SWPC) in Boulder, CO, will begin the dissemination of new International Civil Aviation Organization (ICAO) mandated space weather advisory products. In November 2018, ICAO selected NWS SWPC as one of the three global space weather centers (SWXC) to monitor and provide advisory information on space weather phenomena expected to affect high-frequency radio communications, communications via satellite, Global Navigation Satellite System (GNSS)-based navigation and surveillance systems, and/or pose a radiation risk to aircraft occupants. The new ICAO space weather advisories are produced as conditions warrant according to ICAO Annex 3. Once an advisory is issued, it will be updated at six-hour intervals from the nearest hour after the advisory is issued until the space weather phenomena are no longer detected and/or are no longer expected to have an impact. The SWXCs will maintain a 24-hour watch and issue space weather advisories covering the entire Earth. The ICAO space weather advisories will provide information and services required for safe and efficient aircraft operations that users can employ for decision-making. The intended use of the ICAO space weather advisories is to better prepare flight crews, operators, air navigation service providers, and civil aviation authorities when developing flight plans and operational procedures for managing flights in areas impacted by space weather events. Also, in terms of situational awareness, the space weather advisories need to be properly integrated into the existing docket of aviation considerations as prescribed actions, center requirements, and other functional necessities in order to address the deleterious impacts to aviation in the State’s purview. ICAO space weather advisory users include the NWS, Federal Aviation Administration (FAA), international civil aviation authorities, domestic and international commercial airlines, and private companies.
