Chemosphere
The vaguely defined region of the upper atmosphere in which photochemical
reactions take place. It is generally considered to include the
stratosphere (or the top thereof) and the mesosphere, and sometimes the lower
part of the thermosphere. See atmospheric
shell.
This entire region is the seat of a number of important photochemical
reactions involving atomic oxygen O, molecular oxygen O2, ozone
O3, hydroxyl OH, nitrogen N2, sodium Na, and other
constituents to a lesser degree.
