Aircraft Engine Emissions Impacts on Air Quality, Cloud Formation, and Climate
Aircraft Engine Emissions Impacts on Air Quality, Cloud Formation, and Climate
Session ID#: 79581
Session Description:
Aviation emissions of particles and trace gases are unique in that they affect the quality of the surface air that we breathe, while also altering the composition of the upper troposphere to effect changes in contrail cirrus and climate. The importance of understanding these complex interactions is underscored by the continued rapid growth of the aviation sector, which is projected to increase markedly in coming decades. Yet, observational emissions data are limited for modern engines currently in service, and in-flight data are particularly sparse for aerosol-cloud interactions studies. Key challenges include linking emissions to fuel composition and combustor technology and quantifying the radiative and microphysical properties of contrail cirrus. This session synthesizes process-based implications of observations and models from recent satellite, airborne, ground-based, and test cell measurements of aerosol and trace gas emissions, contrail cirrus, and aviation’s impacts on air quality, human health, and Earth’s radiation and climate.
