WebStratospheric ozone is a naturally-occurring gas that filters the sun's ultraviolet (UV) radiation. This is typically regarded as 'good' ozone since it reduces the harmful effects of ultraviolet (UV-B) radiation. A diminished ozone layer allows more radiation to reach the Earth's surface. Excessive exposure to UV-B at the surface of the earth ... Web30 mei 2016 · The upper limit of the stratosphere, around 50 kilometres, is called the stratopause. Above, we enter the mesosphere. Ozone concentration decreases. Its dissociation, which provided heat, ceases to be a source of heating so that when you go upward, the temperature decreases again. This occurs up to about 85 kilometres away.
