Occam's Razor said:You know you're in the trope because temps tend to decrease as you get higher.
When that stops, you're getting in to the stratosphere. There is still "air" up there (sheesh!), but now the temps increase as you get higher.

But let's clarify:
Troposphere: Decreasing temps.
Tropopause: Constant temp.
And *then* the Stratosphere.
The height of the troposphere is mostly determined by latitude. It's quite low (30,000') in the north and quite high (40,000') around the equator.
