LADCO works with our member states to maintain a regional air quality monitoring network.
Deploying and operating devices that measure air pollution are fundamental activities in the protection of public and ecological health.
The surface monitoring networks in the region collect the following information:
- Meteorology: temperature, winds, humidity and incoming solar radiation
- Criteria Pollutants: CO, NO2, O3, SO2, total volatile organic compounds (VOC), total fine particles (PM2.5), PM10, NH3
- Speciated PM2.5: SO4, NO3, NH4, elemental and organic carbon, dust
- Speciated VOCs
- Mercury: wet deposition and litter fall
- Wet and dry deposition of gaseous pollutants
- Visibility impairment in Class I areas
LADCO works with our member states to ensure that the monitoring network in the region meets Clean Air Act statutory requirements and provides accurate and timely information on the concentrations of different air pollutants. Although we typically don’t operate the monitoring sites directly, LADCO’s work in this area focuses on identifying what should be measured, where to put new monitors, and analyzing data from existing monitors.
Every 5 years states are required by the Clean Air Act to review their air pollution monitoring networks. LADCO coordinates the periodic monitoring network reviews for our member states. Click the links below to view the results of recent monitoring network reviews.
Analyses of trends in the monitoring data are used by our member states to track the effectiveness of emissions reduction programs, demonstrate compliance with federal air pollution regulations and to explore the interactions between regional climate and pollution. In addition to working with the static surface monitors, LADCO has a history of facilitating and sponsoring targeted field campaigns to investigate persistent air quality problems in our region. Examples include the 20xx Winter Nitrate Study [add link] and the 2017 Lake Michigan Ozone Study [add link].
