NYS Ambient Air Quality Report for 2020

Summary tables of air pollution data are organized by DEC Region. Data is available for the traditional air pollutants. These tables will generally indicate the number of observations, maximum values, and a comparison with the National Ambient Air Quality Standards. Annual averages for 2020 and past years are available below.

All network data are submitted to the EPA and can be accessed via the EPA Air Quality System (AQS) API (leaves DEC website) in standard units. Summary information for the criteria pollutants are available from EPA using the Monitor Values Report service (leaves DEC website). For more information, contact us dar.web@dec.ny.gov.
