Uranus' Tropospheric Temperature Profile
This is the temperature profile of Uranus' troposphere. The temperature becomes cooler with height until the tropopause, or "top" of the troposphere is reached. The tropopause is defined to be the altitude where the temperature is lowest in this region of the atmosphere.
The methane clouds of Uranus are located in this region of the atmosphere.
The graph shows that the temperature goes from about 120 kelvins (-243° F) to about 55 K (-370° F) in 100 km (62 miles or 328,000 ft.). Compare the changes in the troposphere with those in the stratosphere.
