Ozone measurement refers to the process of detecting and quantifying the concentration of ozone (O3) in the atmosphere. This is typically done using specialized instruments such as ozone analyzers, which can provide real-time data on ozone levels. Accurate measurements are crucial for monitoring air quality and understanding the impact of ozone on human health and the environment. Ozone is a gas that occurs both in the Earth's stratosphere, where it protects us from harmful ultraviolet (UV) radiation, and at ground level, where it can be a harmful pollutant. Monitoring ground-level ozone is essential for assessing compliance with air quality standards set by organizations like the Environmental Protection Agency (EPA).
