Vertical Profile Based on Composition

• Homosphere - N2 and O2 are uniformly mixed

• Heterosphere - N2 and O2 are not uniformly mixed

Questions for Thought:

1.  If there were no ozone layer, sketch the vertical distribution of temperature from 0-120 km

2.  The mean lapse rate of the troposphere is 6.5°C per km. If the surface temperature is 30°C, what is the temperature at the top of Mt. Everest which is 9 km above the surface?

3.  If the surface temperature is 30°C and the temperature at the top of Mt. Everest is -30°C, what is the mean tropospheric lapse rate?
