The Mid-America Regional Council Air Quality Program has begun issuing daily air quality alerts for the 2011 ozone season.

The Mid-America Regional Council Air Quality Program has begun issuing daily air quality alerts for the 2011 ozone season.


“Ozone season” is the 7-month period between April 1 and Oct. 31 when ozone pollution is most likely to reach levels that cause health concerns. When ozone pollution levels are expected to be high, an ozone alert is issued to warn residents to take actions that protect their health and reduce pollution.


Ozone pollution can cause wheezing, coughing and difficulty breathing even in healthy adults, and it can be especially harmful to children, seniors or people with breathing or heart problems.


The daily SkyCast uses a color code to indicate what type of air quality is expected the next day:




“Green” SkyCast indicates healthy air, when low concentrations of ozone pollution are expected.

“Yellow” SkyCast indicates moderate concentrations of ozone pollution with some increased health risk.

“Orange” and “Red” SkyCasts indicate ozone alert days with unhealthy concentrations of ozone pollution.
