An Overview of Uranus' Atmospheric Structure
As on Earth, the atmosphere of Uranus consists of a troposphere, stratosphere, mesosphere, and thermosphere. The troposphere
is the region where the visible clouds are to be found. The stratosphere
, as on Earth, is a region where the atmosphere warms. Unlike the Earth however, where stratospheric warming is caused by the presence of ozone, the causes of the warming of the Uranian stratosphere are the hazes of methane to be found there. The mesosphere
of Uranus, as on other planets, is a static region, a region of balance between incoming and outgoing energy. The thermosphere
is the other region of the atmosphere where the atmosphere warms. The ionosphere
is the region of the atmosphere that is filled with charged particles. For a picture showing how the temperature changes in whole atmosphere, click here
