Monitoring air quality (for example collecting continuous and quality data) is integral and critical to detecting air pollutants and to ensuring information sharing with the public, policy-makers, and regulatory compliance. Air quality monitoring is also one of the first and necessary steps for quantifying the health impacts from air pollution and monitoring progress towards reducing air pollution. The main pollutants (e.g. particulate matter [PM], nitrogen dioxide, and tropospheric ozone) should be monitored continuously and consistently. Sharing these high-quality and standardized data publicly is essential to raise awareness and encourage decision-makers to take action.
