CONT

Today Earths atmosphere can be divided into different regions described by the pattern of the temperature distribution, physiochemical processes or dynamic and kinetic processes. ... The distribution of various physiochemical processes is ... divided into four regions. The ozonosphere, lying roughly between 10 and 50 km, is the region where there is an appreciable ozone concentration ... The neutrosphere is the shell below 70 to 80 km which is relatively unionised. The ionosphere, the shell starting at 70 to 80 km, is the region in which ionisation of one or more of the atmospheric compounds is significant. The chemosphere, with no very definite height limits, is the region in which photochemical reactions take place.

OBS

Neutral atmosphere [is a] term used in an ionospheric context to describe the nonionized component of the atmosphere.
