Abstract:

As the popularity of and global access to air travel expands, quantifying its impact on climate and air pollution becomes increasingly important. However, the spatial-temporal distribution of aircraft emissions and their byproducts span many orders of magnitude, as contrail development begins within seconds, but can spread to the kilometer-scale and persist for hours. The wide range of spatial and temporal scales makes it difficult to obtain detailed knowledge of the composition and evolution of emissions from measurements or modeling studies alone. In an attempt to increase understanding, this project simulates the short-term, near- and far-field evolution of aircraft exhaust aerosol and contrail particles and gases with two computer models: GATOR-GCMOM and an LES model. Together, these two models simulate phenomena spanning a spatial range from millimeters to thousands of kilometers. Detailed microphysical processes in the models are validated and improved with field measurements from NASA’s ACCESS-2 campaign, so that the models may provide more credible estimates of impacts on climate and atmospheric composition when used at the regional and global scale.
