Les relations entre le Soleil et la Terre

Abstract

The Earth's atmosphere evolution through geological times has induced significant changes in its composition. The properties of today's atmosphere, due in particular to the presence of oxygen, show strong evidence of the Sun–Earth relationship. The influence of solar activity will be presented, concerning the neutral and ionised atmosphere including the magnetosphere, the thermosphere down to the troposphere, and climate as well as the various consequences on our environment (space weather).
