In meteorology, the measure of a height of an airborne object in respect to a constant pressure surface or above mean sea level.
Vertical distance measurements in the "down" direction are commonly referred to as depth.
The Earth's atmosphere is divided into several altitude regions:[3]
- Troposphere — surface to 8000 m / 5 miles at poles – 18,000 m / 11 miles at equator, ending at the Tropopause.
- Stratosphere — Troposphere to 50 km /31 miles
- Mesosphere — Stratosphere to 85 km /53 miles
- Thermosphere — Mesosphere to 675 km / 420 miles
- Exosphere — Thermosphere to 10,000 km /6200 miles
