AB: The MIRAGE/IMPEX program provided a unique opportunity to observe OH within a variety of environments ranging from a large urban mega-city, rural farmland, to the marine. Depending on the SO₂ concentration, OH can produce various amounts of H₂SO₄ within these environments, leading to aerosol formation and growth. Measured OH and H₂SO₄ concentrations from the MIRAGE/IMPEX study will be presented including some of the largest ambient H₂SO₄ concentrations observed by our group. Comparisons of model simulated OH will also be presented.
