      Weaver, C. P.; Cooter, E.; Gilliam, R.; Gilliland, A.; Grambsch, A.; Grano, D.; Hemming, B.; Hunt, S. W.; Nolte, C.; Winner, D. A.; Liang, X-Z.; Zhu, J.; Caughey, M.; Kunkel, K.; Lin, J-T.; Tao, Z.; Williams, A.; Wuebbles, D. J.; Adams, P. J.; Dawson, J. P.; Amar, P.; He, S.; Avise, J.; Chen, J.; Cohen, R. C.; Goldstein, A. H.; Harley, R. A.; Steiner, A. L.; Tonse, S.; Guenther, A.; Lamarque, J-F.; Wiedinmyer, C.; Gustafson, W. I.; Leung, L. R.; Hogrefe, C.; Huang, H-C.; Jacob, Daniel James; Mickley, Loretta J.; Wu, S.; Kinney, P. L.; Lamb, B.; Larkin, N. K.; McKenzie, D.; Liao, K-J.; Manomaiphiboon, K.; Russell, A. G.; Tagaris, E.; Lynn, B. H.; Mass, C.; Salathé, E.; O, S. M.; Pandis, S. N.; Racherla, P. N.; Rosenzweig, C.; Woo, J-H. (American Meteorological Society, 2009)
      This paper provides a synthesis of results that have emerged from recent modeling studies of the potential sensitivity of U.S. regional ozone (O3) concentrations to global climate change (ca. 2050). This research has been ...
    • Radiative forcing from tropospheric ozone calculated with a unified chemistry-climate model 

      Mickley, Loretta J.; Murti, P. P.; Jacob, Daniel James; Logan, Jennifer A.; Koch, D. M.; Rind, D. (Wiley-Blackwell, 1999)
      We have developed a global model for the study of chemistry-climate interactions by incorporating a detailed simulation of tropospheric ozone-NOx-hydrocarbon chemistry within a general circulation model (GCM). We present ...
    • Radiative forcing in the 21st century due to ozone changes in the troposphere and the lower stratosphere 

      Gauss, M.; Myhr, G; Pitari, G; Prather, M.J.; Isaksen, I; Berntsen, T; Brasseur, G; Dentener, F; Derwent, R; Hauglustaine, D; Horowitz, L; Jacob, Daniel James; Johnson, M; Law, K; Mickley, Loretta J.; Müller, J; Plantevin, P; Pyle, J; Rogers, H; Stevenson, D; Sundet, J; van Weele, M; Wild, O (Wiley-Blackwell, 2003)
      Radiative forcing due to changes in ozone is expected for the 21st century. An assessment on changes in the tropospheric oxidative state through a model intercomparison (“OxComp”) was conducted for the IPCC Third Assessment ...
    • Regional warming from aerosol removal over the United States: Results from a transient 2010–2050 climate simulation 

      Mickley, Loretta J.; Leibensperger, E; Jacob, Daniel J.; Rind, D. (Elsevier BV, 2012)
      We use a general circulation model (NASA Goddard Institute for Space Studies GCM 3) to investigate the regional climate response to removal of aerosols over the United States. We perform a pair of transient 2010–2050 climate ...
    • Sensitivity of population smoke exposure to fire locations in Equatorial Asia 

      Kim, Patrick S.; Jacob, Daniel James; Mickley, Loretta J.; Koplitz, Shannon; Marlier, Miriam E.; DeFries, Ruth S.; Myers, Samuel S.; Chew, Boon Ning; Mao, Yuhao H. (Elsevier BV, 2015)
      Land clearing by fire in Equatorial Asia, a substantial fraction for conversion to oil palm plantations, can lead to high smoke concentrations across this densely populated region and represents a serious public health ...
    • Sensitivity of US Air Quality to Mid-Latitude Cyclone Frequency and Implications of 1980–2006 Climate Change 

      Leibensperger, Eric Michael; Mickley, Loretta J.; Jacob, Daniel J. (Copernicus Publications, 2008)
      We show that the frequency of summertime mid-latitude cyclones tracking across eastern North America at 40°–50° N (the southern climatological storm track) is a strong predictor of stagnation and ozone pollution days in ...
    • Tropospheric Bromine Chemistry: Implications for Present and Pre-Industrial Ozone and Mercury 

      Parrella, J. P.; Jacob, Daniel J.; Liang, Q.; Zhang, Y.; Mickley, Loretta J.; Miller, Benjamin Franklin; Evans, M. J.; Yang, X.; Pyle, J. A.; Theys, N.; Van Roozendael, M. (European Geosciences Union, 2012)
      We present a new model for the global tropospheric chemistry of inorganic bromine (Bry) coupled to oxidant-aerosol chemistry in the GEOS-Chem chemical transport model (CTM). Sources of tropospheric Bry include debromination ...
    • Uncertainty in preindustrial abundance of tropospheric ozone: Implications for radiative forcing calculations 

      Mickley, Loretta J.; Jacob, Daniel James; Rind, David Michael (Wiley-Blackwell, 2001)
      Recent model calculations of the global mean radiative forcing from tropospheric ozone since preindustrial times fall in a relatively narrow range, from 0.3 to 0.5 W m−2. These calculations use preindustrial ozone fields ...
    • Why Are There Large Differences Between Models in Global Budgets of Tropospheric Ozone? 

      Wu, Shiliang; Mickley, Loretta J.; Jacob, Daniel J.; Logan, Jennifer A.; Yantosca, Robert M.; Rind, David Michael (American Geophysical Union, 2007)
      Global 3-D tropospheric chemistry models in the literature show large differences in global budget terms for tropospheric ozone. The ozone production rate in the troposphere, P(O x ), varies from 2300 to 5300 Tg yr−1 across ...
