Welcome to the Pima County Department of Environmental Quality Air Info Now web site, dedicated to providing current air quality information for the metropolitan Tucson area.  This website was developed with a grant from U.S. EPA and with assistance from The University of Arizona, The American Lung Association and Pima Association of Governments.  Here you will find information on air pollutants, their health effects, activities to help understand air pollution along with historic and current monitoring data.

This page provides links to these areas and also displays a quick snapshot of current air quality conditions. The updating photos show the current visibility from the rooftop of the County's downtown administration building. In the table below are air quality index (AQI) values, descriptors and applicable cautionary statements for the most currently polled pollution data.

We also have additional resources on products to help manage the air quality inside your home.
