Definitions for "Stratospheric ozone"
ozone formed in the stratosphere from the conversion of oxygen molecules by solar radiation; ozone found there absorbs much ultraviolet radiation and prevents it from reaching the earth.
See ozone layer.
Located 10 to 30 kilometers (6 to 18 miles) above the surface of the earth, it is considered "good" ozone because it blocks harmful ultraviolet (UV) radiation from the sun.
