Air quality monitoring is the process of measuring and assessing the levels of pollutants in the air to determine the overall quality of the air in a specific location. This includes monitoring for pollutants such as particulate matter, ozone, carbon monoxide, sulfur dioxide, and nitrogen dioxide, among others. Air quality monitoring is crucial for assessing the impact of emissions from vehicles, industry, and other sources on public health and the environment. Monitoring data can be used to identify pollution hotspots, track air quality trends over time, and inform decision-making to improve air quality. Various methods are used for air quality monitoring, including stationary monitoring stations, mobile monitoring vehicles, satellite remote sensing, and low-cost sensors. Data from monitoring stations are typically reported to government agencies and the public, and can be used to develop air quality regulations and policies.
