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.
