DNR launches updated air quality map

The Wisconsin Department of Natural Resources (DNR) has improved its air quality data map to help the public stay “air aware.”

The map displays real-time data from the state’s air quality monitoring network and provides a color-coded guide to pollution levels based on the Air Quality Index (AQI).

The latest updates offer a more intuitive and user-friendly experience, making it easier to stay informed about air quality. Changes include:

• A new advisory banner, prominently displayed as a top scrolling bar, ensures that critical air quality updates are instantly visible.

• A dedicated “News” text box on the landing page highlights important updates, including air quality advisories and other essential information.

• Enhanced navigation features, including a sleek set of map menu icons on the right-hand side of the screen, eliminates the need to search through dropdown menus — offering an app-like experience for seamless access.

• A new “Orange or Above” AQI filter makes it easier for users to quickly identify when air quality reaches levels that could impact health. During periods of poor air quality across Wisconsin, such as ozone advisories or the wildfire smoke events experienced this summer, users can toggle the map filter to provide clear visual guidance to help communities stay informed and make safer decisions.

In addition to the new monitoring map, the public can also sign up to receive air quality advisory notices from the DNR via email. Visit airquality.wi.gov.
