The National Environmental Satellite, Data, and Information Service (NESDIS) continuously monitors the conditions on the Sun and in the space environment around the Earth, using measurements collected by instruments on satellites operated by NESDIS and partners like NASA as well as ground-based instruments operated by USAF, USGS, and international partners.
The term “space weather” generally refers to conditions resulting from solar activity that can potentially affect Earth, our atmosphere, and the near-Earth space environment.
