  • to study the global warming,
  • to manage the missions intended for Defence (security and defence missions, dual missions),
  • to study the feasibility of the geostationary or high-temporal revisit capability observation.

The Earth Sciences Fields are

  • Climate and meteorology
  • Atmospheric chemistry and average atmosphere
  • Oceanography
  • Continental surfaces, hydrology
  • Solid Earth
  • Tele-epidemiology

TOSCA and CPS

Every year, CNES calls for scientific proposals from space laboratories.

These proposals in the Earth Sciences are examined by TOSCA (Earth, Ocean, Continental Surfaces and Atmosphere committee). TOSCA leans on thematic working groups of experts who are in charge of evaluating the research needs in each discipline. It ensures the connection with the CPS (Committee of the Scientific Programs) which prepares the scientific decisions taken by the Board of directors of CNES.

The CPS examines the scientific interest of the research programs submitted to CNES as well as  the scientific and technical capacity of the proposing laboratories. It emits notices and propositions on the research programs. It formulates, considering the available means, any useful propositions concerning the development of the space research in France.

Composed of a maximum of twelve members chosen by supervisory ministries, it gathers personalities of the scientific world. Its chairman is chosen on proposition of CNES.
