      Comparison of model estimates of the effects of aviation emissions on atmospheric ozone and methane (pages 6004–6009)

      Seth C. Olsen, Guy P. Brasseur, Donald J. Wuebbles, Steven R. H. Barrett, Hongyan Dang, Sebastian D. Eastham, Mark Z. Jacobson, Arezoo Khodayari, Henry Selkirk, Andrei Sokolov and Nadine Unger

      Article first published online: 26 NOV 2013 | DOI: 10.1002/2013GL057660

      Key Points

      • Effect of aviation on ozone is more uncertain than previously thought
      • Large differences between state-of-the-art model estimates of aviation effects
      • Aviation NOx ozone effects are nonlinear at high NOx emissions
    2. Effects of plume-scale versus grid-scale treatment of aircraft exhaust photochemistry (pages 5815–5820)

      Mary A. Cameron, Mark Z. Jacobson, Alexander D. Naiman and Sanjiva K. Lele

      Article first published online: 8 NOV 2013 | DOI: 10.1002/2013GL057665

      Key Points

      • For some species, plume-scale and grid-scale differences did not diminish over time
      • Multiple flights enhanced the plume-scale and grid-scale treatment differences
      • Plume-scale treatment decreased O3 production and CH4, CO destruction

      Nadine Unger, Yupu Zhao and Hongyan Dang

      Article first published online: 11 FEB 2013 | DOI: 10.1002/grl.50161

      Key Points

      • Assess 2050 global net chemical climate impact of aviation for new scenarios
      • Aviation net chemical climate impact is a global cooling in present and future
      • Aviation CH4 and nitrate forcing is strongly nonlinear in NOx emission changes

      Estimation of 2006 Northern Hemisphere contrail coverage using MODIS data (pages 612–617)

      David P. Duda, Patrick Minnis, Konstantin Khlopenkov, Thad L. Chee and Robyn Boeke

      Article first published online: 6 FEB 2013 | DOI: 10.1002/grl.50097

      Key Points

      • The first global estimate of contrail coverage with a single satellite imager
      • First use of flight track data to reduce false detections in coverage estimate
      • Less coverage observed over heavy air traffic areas with overlapping contrails

      On the radiative forcing of contrail cirrus contaminated by black carbon (pages 778–784)

      K. N. Liou, Y. Takano, Q. Yue and P. Yang

      Article first published online: 27 FEB 2013 | DOI: 10.1002/grl.50110

      Key Points

      • Black carbon can substantially impact the radiative forcing of contrail cirrus
      • Internal mixing of BC in ice can alter its absorption of solar radiation
      • Radiative forcing analysis for contrail must account for BC contamination

      Sarah T. Bedka, Patrick Minnis, David P. Duda, Thad L. Chee and Rabindra Palikonda

      Article first published online: 27 FEB 2013 | DOI: 10.1029/2012GL054363

      Key Points

      • Quantify contrail properties on a broad scale using 1 year of satellite data
      • Contrail properties are dependent on background
      • Contrail properties vary seasonally but not diurnally

      Key Points

      • Contrail radiative forcing over NH is smaller than most model estimates
      • Contrail radiative forcing depends on background and is defined accurately here
      • Maximum control radiative forcing occurs over the North Atlantic
