The National Academy of Sciences is the U.S. adhering member of Scientific Committee on Solar Terrestrial Physics (SCOSTEP), an interdisciplinary body of the International Science Council (ISC).
Through its programs, SCOSTEP advances scientific knowledge of solar terrestrial physics (STP), supports a globally-aware and engaged STP community, and promotes the development of early-career STP scientists. SCOSTEP provides the necessary scientific framework for international collaboration and dissemination of the derived scientific knowledge, in collaboration with other ISC bodies.
These bodies include the Committee of Space Research (COSPAR), International Association of Geomagnetism and Aeronomy (IAGA), International Association of Meteorology and Atmospheric Sciences (IAMAS), International Astronomical Union (IAU), International Union of Pure and Applied Physics (IUPAP), International Union of Geodesy and Geophysics (IUGG), Scientific Committee on Antarctic Research (SCAR), and the International Union of Radio Science (URSI). SCOSTEP is also a permanent observer at the United Nations Committee on the Peaceful Uses of Outer Space (UNCOPUOS).
