Uranus' Stratosphere

The stratosphere of Uranus is a region of warming as determined by infrared measurements of methane (CH4) in the region. Like the troposphere, the stratosphere is warmed by the sun, warmed by Uranus' interior, and is cooled due to re-radiation to space by the gases of the atmosphere. For a picture showing how the temperature changes in this region, click here.

Uranus' Stratospheric Temperature Profile

This diagram shows the temperature profile of Uranus' stratosphere. The temperature becomes warmer with height until the stratopause, or "top" of the stratosphere is reached. As shown in the figure, the...more

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...more

Uranus' Smog

Besides methane, Uranus' atmosphere contains even more complex molecules. These molecules form layers of smog over the clouds of Uranus, as shown in the picture. ...more

Uranus' Mesosphere

The mesosphere of Uranus is a region of balance between warming and cooling. That essentially means that nothing happens there. Except for diffusion, the atmosphere is still. Upper reaches of the atmosphere,...more

Altitude Changes of the Belts & Zones

On Uranus, as on Jupiter, the winds in the belts and zones blow first in one direction, then in the other direction. The clouds rise up in a belt, and drop down in a zone, as shown in this picture. This...more

Why Uranus looks like a "bullseye"

The clouds on Uranus, like Jupiter, are divided into stripes. On Uranus the stripes are hard to find. The left picture shows the north pole of Uranus. In this picture only the smog can be seen. The clouds,...more
