Besides methane, Uranus' atmosphere contains more sophisticated atmospheric constituents such as ethane gas, acetylene, and diacetylene. All these elements form layers of haze at different altitudes high in the upper stratosphere, as shown in the picture.
Clouds form at a lower altitude in the troposphere.
The diagram shows how the temperature changes in the stratosphere. The temperature goes from about -370 degrees (55 K) to about -243 degrees (120 K). Layers of haze or smog are located throughout this region of the atmosphere.
