From our rooftop pollen samper!

Pollen information updated hourly. The app uses a color coding similar to the AQI coding, but it is not related.

The weekday AQI can also be found on our information line @ 330-375-2545 or by following ARAQMD on Facebook.

Understanding the Air Quality Index

The air quality index (AQI) value is assigned through the measurement of five criteria pollutants: surface ozone, particulate matter, carbon monoxide, sulfur dioxide, and nitrogen dioxide.  Each of these pollutants is assessed relative to standards set by the EPA based upon ambient air quality related to affected groups of people (0-500; 0-100 being the set AQI to meet air quality standards that meet satisfactory human health). Six divisions of the AQI were created to help the general public visualize and understand their region’s ambient air quality in relation to individual health. This is done through the use of colors and values as shown below. If interested in air quality across the United States, refer to AIRNow.
