      Toohey, Darin; McConnell, John; Avallone, Linnea; Evans, Wayne (American Meteorological Society, 2010)
      Aircraft emissions impact the atmosphere in a variety of ways, including enhancing greenhouse gases, especially water vapor and carbon dioxide, in the upper troposphere and lower stratosphere, forming persistent contrails, ...
    • Impact of Aviation on Climate: Research Priorities 

      Brasseur, Guy P.; Gupta, Mohan (American Meteorological Society, 2010)
      Though presently small in magnitude, aviation?s future impact on climate will likely increase with the absence of effective mitigation measures. With the exception of CO2 emissions, climate impacts of aviation emissions ...
