The Scientific Committee on Solar-Terrestrial Physics (SCOSTEP) is a thematic body of the International Science Council (ISC). SCOSTEP promotes ISC’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 ISC 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.


Statement on Inclusion and Diversity

Dear SCOSTEP colleagues,

As a thematic organization of the International Science Council (ISC), SCOSTEP seeks
to uphold principles of inclusivity and diversity, to defend the free and responsible
practice of science, to promote equitable opportunities and to oppose all forms of
discrimination.  We call on the SCOSTEP members to consider these points as your close issue. 

We put this statement together with the attached ISC statement.

With best regards,
Kazuo Shiokawa and Daniel Marsh, on behalf of the SCOSTEP Bureau

A total of 37 clever designs were submitted for consideration.  After much thought, the PRESTO committee selected the design provided by Mr. Vishal Jagatsing Pawar.  Mr. Pawar is a Master's Degree Candidate in Atmospheric and Space Science at Pune University in Maharashtra, India.

Congratulations to Mr. Vishal Pawar and thanks to all who submitted a design


In response to the current difficulties of hosting meetings in person, SCOSTEP-PRESTO is hosting online seminars to deliver the latest scientific topics and/or instructive review presentations on solar-terrestrial physics related to SCOSTEP's PRESTO program.

We are happy to announce that the recordings of the first four SCOSTEP/PRESTO​ ​online seminars are ​now ​available​. To access these videos and to register for upcoming seminars click on SCOSTEP-PRESTO ONLINE SEMINAR SERIES
