Air Quality and Meteorological Information System (AQMIS) Information

The Air Quality and Meteorological Information System (AQMIS) is a web-based source for real-time (and historical) air quality and meteorological data. It is used by various groups such as state and local officials and the public to track air quality. It is also used for smoke management and air pollution forecasting. The real-time data are so new that they have not undergone a rigorous QA process at the time of release and hence the real-time data are considered preliminary. Further information and details about AQMIS can be found by clicking on the links below.
