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 Council for Science (ICSU). The complete list of U.S. Coordinating Group members can be found on the Membership page.
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 ICSU 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).
Variability of the Sun and Its Terrestial Impact (VarSITI)
On January 13, 2014, SCOSTEP launched a new scientific program: Variability of the Sun and Its Terrestial Impact (VarSITI). Varsiti will study the causes and consequences of weak solar activity during cycle 24. This program has four components:
- Solar Evolution and Extrema (SEE)
- International Study of Earth Affecting Solar Transients (ISEST)/MiniMax24
- Specification and Prediction of the Coupled Inner-Magnetospheric Environment (SPeCImeN)
- Role Of the Sun and the Middle atmosphere/thermosphere/ionosphere In Climate (ROSMIC)
Three of these have project co-leaders from the United States:
- SEE: Petrus Martens, Montana State University
- ISEST: Jie Zhang, George Mason University; and Nat Gopalswamy, NASA Goddard
- SPeCIMEN: Jacob Bortnik, University of California, Los Angeles
VarSITI will promote more communication between solar and geospace/terrestrial scientists. The program’s activities are coordinated through:
- Campaign data analysis from the Sun and the Earth
- Targeted workshops, conducted by the sub-groups of each project to focus on problem-solving, which can lead to later symposia presentations
- Web pages (http://www.varsiti.org, hosted in Bulgaria)
- Mailing lists (hosted by Nagoya University, Japan)
- Quarterly newsletters (hosted by Nagoya University, Japan)
SCOSTEP 13th Quadrennial Solar-Terrestrial Symposium: October 12-18, 2014 in Xi’an, China
This was the thirteenth in the series of Solar-Terrestrial Physics Symposia organized by SCOSTEP and held approximately every four years. In 2013, the Climate and Weather in the Sun-Earth System (CAWSES) program ended, and the new program known as the Variability of the Sun and Its Terrestrial Impact (VarSITI) started. The underlying theme of SCOSTEP scientific programs is the way the Sun affects Earth over various time scales. The VarSITI program expands the solar terrestrial physics to a broader context to star-planet interaction, which might further our scientific understanding of the Sun-Earth connection.
This October, 2014 symposium, known as STP13 for short, highlighted results obtained during the CAWSES program and the new results from the VarSITI program. STP13 invited talks and presentations can be found online on the SCOSTEP website.
SCOSTEP ‘Comic Books’
SCOSTEP has been sponsoring a series of ‘Comic Books’ designed to raise the awareness of the general public, and young people in particular, about issues in solar-terrestrial science. Originally produced in Japanese, the books have been translated into English and multiple other languages. Sample titles include “What are the Polar Regions?!" and “What is the Geomagnetic Field?!.” To access the complete collection of SCOSTEP ‘Comic Books,’ please visit the SCOSTEP website.
U.S. SCOSTEP Coordinating Group Activity
On December 11, 2014, the U.S. Coordinating Group of SCOSTEP held its second conference call. In the conference call, areas of mutual interest between SCOSTEP and other international unions were discussed. In addition, an overview was provided of SCOSTEP’s current initiatives.
