SUMMARY:The 2017 Lake Michigan Ozone Study\, Physics Department Colloq
 uium\, Brad Pierce\, UW Space Sciences and Engineering Center
DESCRIPTION:The 2017 Lake Michigan Ozone Study (LMOS 2017) was a colla
 borative\, multi‐agency field study of ozone chemistry and meteorolo
 gy along the Wisconsin‐Illinois Lake Michigan shoreline using a comb
 ination of aircraft\, ground‐based and ship‐based measurements. Th
 e goal of the study was to better understand ozone formation and trans
 port around Lake Michigan\; in particular\, why ozone concentrations a
 re generally highest along the lakeshore and drop off sharply inland a
 nd why ozone concentrations peak in rural areas far from major emissio
 n sources.  Field activities were conducted from May 22‐June 22\, 20
 17 and included two aircraft (one for remote sampling and one for insi
 tu profiling)\, two ground based super sites (Sheboyhgan\, WI and Zion
 \, IL) with both remote sensing and insitu measurements\, two mobile s
 ampling platforms measuring lakeshore‐inland ozone concentration gra
 dients\, and additional ground‐based remote sensing instruments coll
 ocated at several other shoreline locations. Air quality and meteorolo
 gical forecasts provided flight planning guidance and in‐field evalu
 ation of model prediction skill during the campaign. This talk provide
 s an overview of the LMOS 2017 field campaign\, a summary of the measu
 rements conducted during the LMOS 2017 field campaign and preliminary 
 results\, and a summary of preliminary model/measurement comparisons h
 ighlighting the difficulties in predicting coastal ozone concentration
 s along the western shore of Lake Michigan.
