The International Space Environment Services is a space weather service organization currently comprised of 22 Regional Warning Center around the globe, four Associate Warning Centers, and one Collaborative Expert Center (European Space Agency). ISES is a Network Member of the International Council for Science World Data System (ICSU-WDS) Meteorological Organization (WMO) and other international organizations, including the Committee on Space Research (COSPAR), the International Union of Radio Science (URSI), and the International Union of Geodesy and Geophysics (IUGG). In response to a letter from UNCOPUOS in June 2022, representatives from WMO-ISES-COSPAR met in Coimbra in September 2022, and agreed on the Coimbra Declaration as the basis for their partnership - The WMO-ISES-COSPAR Coimbra Declaration. The WMO-ISES-COSPAR Coordination Team will continue to drive this partnership.
The mission of ISES is to improve, to coordinate, and to deliver operational space weather services. ISES is organized and operated for the benefit of the international space weather user community.
ISES Members share data and forecasts and provide space weather services to users in their regions. The Members provide a broad range of services, including: forecasts, warnings, and alerts of solar, magnetospheric, and ionospheric conditions; extensive space environment data; customer-focused event analyses; and long-range predictions of the solar cycle. While each RWC concentrates on its own region, ISES serves as a forum to share data, to exchange and compare forecasts, to discuss user needs, and to identify the highest priorities for improving services.
ISES works in close cooperation with the World Meteorological Organization, recognizing the mutual interest in global data acquisition and information exchange, in common application sectors, and in understanding and predicting the coupled Earth-Sun environment.
