The National Academy of Sciences (NAS)/National Research Council (NRC) Committee on Solar-Terrestrial Research (CSTR) of the Board of Atmospheric Sciences and Climate is charged with looking after the “health of solar-terrestrial research” in the United States. CSTR was established in 1965 for the purposes of

  • responding to requests from government agencies for scientific advice on projects or programs in solar-terrestrial research,
  • providing a mechanism for organizing cooperative projects among U.S. scientists,
  • taking initiatives in scientific planning as needed, and
  • coordinating U.S. researches with those in other countries.
