Air Quality Forecast

What & How NJDEP Monitors

New Jersey has been monitoring air quality since 1965. Pollution levels have improved significantly over the decades as a result of state, regional and national air pollution reduction efforts. The graphs available below illustrate more recent trends in pollutant concentrations.

Air Quality Data Downloads

NJDEP reviews and edits the air monitoring data it collects, and at the end of each calendar quarter, submits that data to the U.S. Environmental Protection Agency’s Air Quality System (AQS) database. The data available on our NJDEP website has not yet been reviewed.
