Ozone Layer: About 90% of the ozone in the Earth's atmosphere is found in a layer between 22 and 30 km above the surface. This layer is within a region of the atmosphere called the stratosphere.

OZONE LAYER An atmospheric layer that contains a high proportion of oxygen that exists as ozone. It acts as a filtering mechanism against incoming ultraviolet radiation. It is located between the troposphere and the stratosphere, around 9.5 to 12.
Ozone layer - a thin protective layer of ozone gas in the stratosphere.
Polar vortex - cyclonic motion near the pole. Very cold, especially in winter.
Ozone layer the region of the stratosphere containing the bulk of atmospheric ozone The ozone layer lies approximately 15-40 kilometers (10-25 miles) above the Earth's surface, in the stratosphere.
ozone layer: a place in the stratosphere (about 10-50 kilometers up) where the high ozone (O3 molecules) concentration shields the Earth from harmful ultraviolet radiation.
Ozone Layer The layer of ozone that begins approximately 15 km above Earth and thins to an almost negligible amount at about 50 km, shields the Earth from harmful ultraviolet radiation from the sun.

Ozone exists in the upper atmosphere ozone layer as well as at the earth's surface. Ozone at the earth's surface causes numerous adverse health effects and is a criteria air pollutant. It is a major component of smog.
ozoneOzone measurements are given in Dobson units and are integers with 3 significant figures. A Dobson Unit represents the physical thickness of the ozone layer if it were brought to the earth's surface.
