  "definition": "1. The region of the atmosphere above the troposphere. The stratosphere extends from about 10km to about 50km in altitude. Commercial airlines fly in the lower stratosphere. The stratosphere gets warmer at higher altitudes. In fact, this warming is caused by ozone absorbing ultraviolet radiation. Warm air remains in the upper stratosphere, and cool air remains lower, so there is much less vertical mixing in this region than in the troposphere.\n\n2. The portion of the atmosphere 10-to-25 miles above the earth's surface.\n\n3. Region of the atmosphere between the troposphere and mesosphere, having a lower boundary of approximately 8 km at the poles to 15 km at the equator and an upper boundary of approximately 50 km. Depending upon latitude and season, the temperature in the lower stratosphere can increase, be isothermal, or even decrease with altitude, but the temperature in the upper stratosphere generally increases with height due to absorption of solar radiation by ozone.\n\n4. Second layer of the atmosphere, extending from about 19 to 48 kilometers (12 to 30 miles) above the earth's surface. It contains small amounts of gaseous ozone (O₃), which filters out about 99 percent of the incoming harmful ultraviolet (UV) radiation. Most commercial airline flights operate at a cruising altitude in the lower stratosphere. See ozone layer, ultraviolet radiation.\n\n5. The region of the atmosphere above the troposphere. The stratosphere extends from about 10-50 km (6-31 miles) in altitude. Commercial airlines fly in the lower stratosphere. The stratosphere gets warmer at higher altitudes. In fact, this warming is caused by ozone absorbing ultraviolet radiation. Warm air remains in the upper stratosphere, and cool air remains lower, so there is much less vertical mixing in this region than in the troposphere.\n\n6. The region of the atmosphere extending from the top of the troposphere to the base of the mesosphere, an important area for monitoring stratospheric ozone.\n\n7. The region of the atmosphere located about 10-50km above the surface of the Earth. It contains the benefical ozone layer.\n\n8. The Stratosphere extends around 31 miles (50 km) down to anywhere from 4 to 12 miles (6 to 20 km) above the Earth's surface. This layer holds 19 percent of the atmosphere's gases but very little water vapor. In this region the temperature increases with height. Heat is produced in the process of the formation of Ozone and this heat is responsible for temperature increases from an average -60°F (-51°C) at tropopause to a maximum of about 5°F (-15°C) at the top of the stratosphere. This increase in temperature with height means warmer air is located above cooler air. This prevents \"convection\" as there is no upward vertical movement of the gases. As such the location of the bottom of this layer is readily seen by the 'anvil-shaped' tops of cumulonimbus clouds.\n\n9. The stratosphere and stratopause stretch above the troposphere to a height of 50 km. It is a region of intense interactions among radiative, dynamical, and chemical processes, in which horizontal mixing of gaseous components proceeds much more rapidly that vertical mixing. The stratosphere is warmer than the upper troposphere, primarily because of a stratospheric ozone layer that absorbs solar ultraviolet energy.\n\n10. Region of the atmosphere above the troposphere. The stratosphere extends from about 10-50 km (6-31 miles) in altitude. Commercial airlines fly in the lower stratosphere. The stratosphere gets warmer at higher altitudes. In fact, this warming is caused by ozone absorbing ultraviolet radiation. Warm air remains in the upper stratosphere, and cool air remains lower, so there is much less vertical mixing in this region than in the troposphere.\n\n11. Layer of the atmosphere that starts about 6 to 9 miles above the Earth’s surface at mid-latitudes and lies above the troposphere. The stratosphere contains small amounts of gaseous ozone, which filters out about 99 percent of the incoming ultraviolet radiation.\n\n12. The layer of the atmosphere that starts about 6 to 9 miles above the Earth’s surface at mid-latitudes and lies above the troposphere. The stratosphere contains small amounts of gaseous ozone, which filters out about 99 percent of the incoming ultraviolet radiation.\n\n13. Extends from 4 to 12 miles (6 to 20 km) above the Earth's surface to around 31 miles (50 km) [Original source: https://www.weather.gov/jetstream/layers].",
