Scientific Committee on Solar-Terrestrial Physics


The Scientific Committee on Solar-Terrestrial Physics (SCOSTEP) is an interdisciplinary body of the International Council for Science (ICSU). SCOSTEP promotes ICSU’s mission to strengthen international science for the benefit of society. SCOSTEP runs international interdisciplinary scientific programs and promotes solar-terrestrial physics research by providing the necessary scientific framework for international collaboration and dissemination of the derived scientific knowledge in collaboration with other ICSU bodies. SCOSTEP is a permanent observer at the United Nations Committee on the Peaceful Uses of Outer Space (UNCOPUOS).

SCOSTEP’s Secretariat Office is currently hosted by the Institute for Scientific Research at Boston College. From 2010 to 2019, it was hosted by the  Centre for Research in Earth and Space Science (CRESS) at York University in Toronto, Canada, at NCAR from 2006 to 2010, and within NOAA from 1995 to 2006.
