Air quality forecasts come from the EPA website They rely on data from the Missouri Department of Natural Resources concerning ground-level ozone and particle pollution.

Understanding the Air Quality Index

EPA created its color-coded index to help people figure out how air quality can affect their health. Colors correspond to different levels of health concern, and numerical values correlate with the department's data. For example, an AQI value of 100 corresponds to the federal standard for a pollutant, or the level EPA has set to protect public health.

Using the Air Quality Index can help you plan your activities, particularly on days when the forecast is orange to maroon.
