The Atmosphere, the Ocean and Environmental Change (GG 140)
Pressure and density decrease exponentially with altitude in the atmosphere. This leads to buoyancy effects in the atmosphere when parcels of air are heated or cooled, or raised or lowered in the atmosphere. Temperature varies in a more complicated way with altitude in the atmosphere, with several inversions which occur at the boundaries of the various layers of the atmosphere. Solar radiation interacts differently with the gases that compose each layer of the atmosphere which affects which wavelengths of radiation are able to reach the surface of the Earth.
