Abstract Number: 467 Working Group: Regional and Global Air Quality and Climate Modeling
Abstract Spring and summertime ozone pollution remains a challenging air quality problem along the coast of Lake Michigan. Production of ozone over Lake Michigan combined with onshore daytime “lake breeze” airflow is thought to increase ozone concentrations preferentially at locations within a few kilometers of the shore. A collaborative field campaign (Lake Michigan Ozone Study 2017, LMOS 2017) took place during May and June 2017 to gather high spatio-temporal resolution data to address this issue. The campaign provided extensive observational datasets regarding ozone, its precursors, particulate matter, and meteorology associated with ozone events through a combination of airborne, ship, mobile lab, and ground-based sites. In addition, chemical transport model (CTM) and meteorological forecast tools were employed. The ultimate goal of the campaign is to allow evaluation and improvement of CTMs used for regulatory and research purposes.
An overview of the campaign and its experience sampling atmospheric features relevant to scientific and air quality management goals will be discussed. Main observing systems during the campaign included GeoTASO (the airborne version of the future geostationary TEMPO instrument for remote sensing of column O3, NO2 and formaldehyde), aircraft in situ ozone and NO2 (Scientific Aviation), mobile lab trace gases (EPA region 5 GMAP), AirHarp (the airborne version of the Cubesat Hyper-Angular Rainbow Polarimeter HARP), boundary layer profiling and column O3, NO2 and formaldehyde using a network of Pandora spectrometers and ceilometers, and on-lake sampling from the NOAA research vessel R5503. Two ground stations (Sheboygan WI and Zion IL) included meteorological vertical profiling, and in situ gas and aerosol sampling of a wide variety of aerosol, VOC, NOy, and oVOC compounds. LMOS 2017 partners include LADCO and its member states, NASA, NOAA, EPA, EPRI, Scientific Aviation, University of Iowa, University of Minnesota, University of Wisconsin, and the University of Northern Iowa.
