 Atmospheric chemistry

The chemistry of gases, particles and droplets in planetary atmospheres. Chemical conversion competes with radiation, transport, mixing and removal to surfaces, so local equilibrium is not a general assumption.

Atmospheric chemistry is the study of the chemical composition of the Earth's atmosphere and the chemical reactions that occur within it. It encompasses various processes that affect the atmosphere's composition, including the interactions between gases, aerosols, and other particles. This field examines both natural and anthropogenic (human-made) sources of atmospheric constituents and how they influence air quality, climate, and atmospheric processes.
