The stratosphere is the layer of the Earth's atmosphere located above the troposphere and extends to about 50 \mathrm{~km} above the Earth's surface. It is characterized by a relatively stable temperature profile and contains several gases, including dioxygen ( \mathrm{O}_2 ), \, \, dinitrogen \, \, ( \mathrm{N}_2 ), ozone ( \left.\mathrm{O}_3\right), and trace amounts of other gases. Carbon dioxide \left(\mathrm{CO}_2\right) is also present in the Earth's atmosphere, but it is not a significant component of the stratosphere. The concentration of \mathrm{CO}_2 is highest in the troposphere, which is the layer of the atmosphere closest to the Earth's surface.\mathrm{CO}_2 is an important greenhouse gas that contributes to global warming, but its concentration in the stratosphere is relatively low.
