Homosphere

From Glossary of Meteorology



homosphere[edit | edit source]

The lower portion of a two-part division of the atmosphere according to the general homogeneity of atmospheric composition; opposed to the heterosphere.

The homosphere is the region in which there is no gross change in atmospheric composition, that is, all of the atmosphere from the earth's surface to about 80 or 100 km.
See atmospheric shell.
