An Ambient Air Quality Monitoring System, often referred to as an Ambient Quality Monitoring System (AQMS) or Ambient Air Monitoring System, is a network of instruments and sensors designed to continuously measure and assess the quality of the air in a specific geographical area, typically in outdoor environments. The primary objective of AQMS is to monitor the concentrations of various air pollutants and provide information about air quality to support environmental management, public health protection, and regulatory compliance.
