APCD’s monitoring sites are connected to the Metro AIR NET database, which allows APCD to gather and post raw monitoring data to the internet approximately one hour after collection. Please note this raw data has not been quality assured yet.

Visit the Metro AIR NET page to find current and recent air monitoring data for Jefferson, Bullitt, and Oldham Counties in Kentucky. Current air quality data from the New Albany and Charlestown State Park monitors in southern Indiana are also available through the Indiana Department for Environmental Management (IDEM).

Historical air monitoring data for Jefferson County, Kentucky can be found in the table below.  (Note that each link goes to the report that includes data for that month; the report was issued the next month.)
