The stratosphere is about 20 miles thick. It starts at about 10 miles or 60,000 feet above the ground and goes to about 30 miles or 160,000 ft above the ground. Temperatures start to increase through this layer. They start at about -76°F and increase to about 40°F in the stratopause (top part). The stratosphere has very thin air made mostly of oxygen.
