One-dimensional model
From Glossary of Meteorology
one-dimensional model
A mathematical model that simulates variations in chemical composition along one spatial coordinate, usually altitude, as a function of time.
One-dimensional models are usually used to examine the effects of a change in chemistry on the vertical distribution of trace atmospheric constituents, for example, ozone, at a given latitude. The models are fairly cheap and easy to run, but do not represent atmospheric meridional or zonal transport of atmospheric constituents.
