AQS (Air Quality System)

The Air Quality System (AQS) is a program that collects, manages, and reports data on air pollution levels across various locations. It uses a network of monitoring stations that measure pollutants like ozone, particulate matter, and nitrogen dioxide. This data helps government agencies assess air quality, identify pollution sources, and develop policies to protect public health and the environment. AQS ensures that air quality information is accurate, consistent, and accessible for decision-makers and the public.
