    • Annual Distributions and Sources of Arctic Aerosol Components, Aerosol Optical Depth, and Aerosol Absorption 

      Breider, Thomas J.; Mickley, Loretta J.; Jacob, Daniel James; Wang, Qiaoqiao; Fisher, Jenny A.; Chang, Rachel. Y.-W.; Alexander, Becky (Wiley-Blackwell, 2014)
      Radiative forcing by aerosols and tropospheric ozone could play a significant role in recent Arctic warming. These species are in general poorly accounted for in climate models. We use the GEOS-Chem global chemical transport ...
    • Factors Driving Mercury Variability in the Arctic Atmosphere and Ocean over the Past 30 Years 

      Fisher, Jenny A.; Jacob, Daniel James; Soerensen, Anne Laerke; Amos, Helen Marie; Corbitt, Elizabeth Sturges; Streets, David G.; Wang, Qiaoqiao; Yantosca, Robert M.; Sunderland, Elynor M (Wiley-Blackwell, 2013)
      [1] Long-term observations at Arctic sites (Alert and Zeppelin) show large interannual variability (IAV) in atmospheric mercury (Hg), implying a strong sensitivity of Hg to environmental factors and potentially to climate ...
    • A new interpretation of total column BrO during Arctic spring 

      Salawitch, R. J.; Canty, T.; Kurosu, T; Chance, Kelly V.; Liang, Q.; da Silva, A.; Pawson, S.; Nielsen, J. E.; Rodriguez, J. M.; Bhartia, P. K.; Liu, X.; Huey, L. G.; Liao, J.; Stickel, R. E.; Tanner, D. J.; Dibb, J. E.; Simpson, W. R.; Donohoue, D.; Weinheimer, A.; Flocke, F.; Knapp, D.; Montzka, D.; Neuman, J. A.; Nowak, J. B.; Ryerson, T. B.; Oltmans, S.; Blake, D. R.; Atlas, E. L.; Kinnison, D. E.; Tilmes, S.; Pan, L. L.; Hendrick, F.; Van Roozendael, M.; Kreher, K.; Johnston, P. V.; Gao, R. S.; Johnson, B.; Bui, T. P.; Chen, G.; Pierce, R. B.; Crawford, J. H.; Jacob, Daniel James (Wiley-Blackwell, 2010)
      Emission of bromine from sea-salt aerosol, frost flowers, ice leads, and snow results in the nearly complete removal of surface ozone during Arctic spring. Regions of enhanced total column BrO observed by satellites have ...
    • Sources, distribution, and acidity of sulfate–ammonium aerosol in the Arctic in winter–spring 

      Fisher, Jenny A.; Jacob, Daniel James; Wang, Qiaoqiao; Bahreini, Roya; Carouge, Claire C.; Cubison, Michael J.; Dibb, Jack E.; Diehl, Thomas; Jimenez, Jose L.; Leibensperger, Eric M.; Lu, Zifeng; Meinders, Marcel B.J.; Pye, Havala O.T.; Quinn, Patricia K.; Sharma, Sangeeta; Streets, David G.; van Donkelaar, Aaron; Yantosca, Robert M. (Elsevier, 2011)
      We use GEOS-Chem chemical transport model simulations of sulfate–ammonium aerosol data from the NASA ARCTAS and NOAA ARCPAC aircraft campaigns in the North American Arctic in April 2008, together with longer-term data from ...
