What is the ozone layer located troposphere considered?

The ozone layer is primarily located in the stratosphere, not the troposphere. It serves as a protective shield, absorbing the majority of the sun's harmful ultraviolet (UV) radiation. The presence of ozone in the troposphere, however, is considered a pollutant and can have harmful effects on human health and the environment. Overall, the stratospheric ozone layer is crucial for life on Earth, while tropospheric ozone contributes to air quality issues.
