The stratosphere is a region within the atmosphere that lies between the troposphere and the mesosphere.
Its upper boundary is at about 50 kilometres. However, its lower boundary ranges from nearly 8 km at the poles to as much as 15 km at the equator.
Temperatures in the upper stratosphere will often increase with height because of the solar radiation absorbed by ozone inside the ozone layer.
In the lower stratosphere, temperatures may increase, decrease or even stay the same with altitude, depending on the latitude and the season.
However, this is not the case as per data recorded by scientists around the world.« Back to Glossary Index
