Missouri's Air Quality Data
The following information, supplied by the department's Air Pollution Control Program, is provided to help you identify daily ozone highs including any values that exceed the National Ambient Air Quality Standard of .085 ppm. This data is collected hourly from ozone monitors located throughout the state.  Air quality information is available for the St. Louis, Kansas City, Springfield and Outstate areas.  More detailed readings and general information about ozone is found on the department's Environmental Services Program's Air Quality Monitoring Information Web page.
