TOSCA is a multidisciplinary European network of scientists from more than 18 countries whose objective is to provide a better understanding of the hotly debated role of the Sun in climate change. This action aims at assessing the various contributions of solar variability to the Earth’s climate by bringing together solar physicists, space scientists, atmospheric scientists, climate modellers, paleoclimatologists, and more.
The International Union of Geodesy and Geophysics (IUGG) is the international organization dedicated to advancing, promoting, and communicating knowledge of the Earth system, its space environment, and the dynamical processes causing change.
SCOSTEP (Scientific Committee for Solar-Terrestrial Science) seeks opportunities for interaction with national and international programs involving Solar-Terrestrial Physics elements. It provides guidance to the STP discipline centers of ICSU’s World Data Center system. It attempts to develop and sustain student interest in Sun-Earth connections, to promote efficient exchange of data and information between solar and terrestrial scientists in all countries, and to seek projects and programs that cross over traditional boundaries of physical regions and focused scientific disciplines.
COSPAR's objectives are to promote on an international level scientific research in space, with emphasis on the exchange of results, information and opinions, and to provide a forum, open to all scientists, for the discussion of problems that may affect scientific space research. These objectives are achieved through the organization of Scientific Assemblies, publications and other means.
