Wildfire Smoke and Air Quality The LADCO Executive Director has been in the news quite a bit lately talking about the impacts of wildfire smoke on air quality in the region. Learn about what he said and what LADCO is doing to support our member states to address their air pollution management obligations when wildfire smoke enters our region.    Learn More β†’    LADCO Reports on Ozone in the
Great Lakes Region
LADCO recently completed two seminal reports on ground level ozone (smog)
formation in the Great Lakes Region. These reports provide policy makers, researchers,
and the public with the current state of knowledge of ozone in the region.

Regional Haze Progress LADCO uses surface monitoring data and air quality modeling to track progress toward the goal of natural visibility conditions in our region's most scenic areas. Click below to learn more about our collaboration with states, tribes, and Federal Land Managers on reducing regional haze.    Learn More β†’    Mercury Deposition Monitoring Working with our member states, LADCO investigates how mercury pollution patterns change relative to shifts in domestic energy sources and how emerging international sources of mercury impact our region.

The Lake Michigan Air Directors Consortium (LADCO) is a nonprofit air quality research and planning organization. Known as a Multi-Jurisdictional Organization (MJO), LADCO works with federal, state, tribal, and local air agencies to improve air quality in the Great Lakes region. LADCO membership includes state air agencies for: Illinois, Indiana, Michigan, Minnesota, Ohio and Wisconsin. Learn more about some of the services that we provide below and by visiting the About Us section of the website.

What We Do


We coordinate classroom trainings, webinars, and workshops for state air agency staff. These opportunities help to ensure that our state air planners have the necessary information and skills to understand and address air quality issues in the region.

We provide technical air quality support to our member states by performing regional air quality model simulations. We use these models to both understand the causes of air pollution in the region and to explore air pollution mitigation strategies.

Our analyses of observed air pollution and weather trends allow our member states to track their emissions reduction programs, show compliance with regulations, and explore feedbacks between regional climate and air pollution.

We use computer models to simulate and forecast the air pollution emissions from natural and man-made sources. Our emissions forecasts are used by our states to test different control strategies and to demonstrate progress towards meeting their clean air goals.
