Question:
Does air composition change with altitude in the Troposphere? Is oxygen concentration different at an altitude of e.g. 10000m than at sea level?

Replies:
The composition of the atmosphere remain relatively constant up to the ozone layer at an altitude of around 60,000 feet (though that number does vary somewhat).

Larry Krengel

The chemical composition of the atmosphere is very complicated!! It depends on altitude, day vs. night, solar activity, and a lot more. I found the site below that gives some idea of how your "simple" question has a very complicated answer.
