Structure of earth�s atmosphere Temperature (T)
In troposphere (0 to 10-17 km), T decreases uniformly; troposphere heated by IR radiation from Earth�s surface
Temperature minimum occurs at tropopause
In stratosphere (10-17 km to ~ 50 km), T increases with height due to absorption of UV radiation from space (by ozone)
In mesosphere (50 to 100 km), T decreases with height
In thermosphere (at heights >100 km), T increases with height, again due to absorption of UV radiation
