Concept information
Preferred term
Space weather
Definition
- The varying conditions in space and specifically in the near-Earth environment. Space weather is chiefly solar driven, resulting from solar activities such as solar flares, solar wind, and coronal mass ejections that affect magnetosphere, ionosphere, and thermosphere. Non-solar sources such as Galactic cosmic rays, meteoroids, and space debris can all be considered as altering space weather conditions at the Earth. Space weather may affect the performance and reliability of space-borne and ground-based technological systems and can endanger human life or health. The research in this field aims at monitoring and diagnosis of space weather conditions and constructing reliable numerical prediction models. (en)
