The stratosphere is the layer in the atmosphere above the troposphere. The stratosphere reaches from the tropopause to a height of about 50 km.

Temperature in the stratosphere rises with increasing altitude, because the ozone layer absorbs the greater part of the solar ultraviolet radiation. The ozone layer is an absorbing agent that protects life on Earth.
