Abstract:The project developed tools that enable rapid assessment of National Airspace System (NAS) wide and global impacts of aviation emissions on aviation-attributable particulate matter (PM), ozone, and resultant health outcomes for different policy scenarios. The adjoint method, which the tools are based on, provides a computationally efficient way of calculating the sensitivities of an objective function with respect to multiple model inputs. The project enhanced the existing tools in terms of the domains and impacts covered, and in terms of uncertainty quantification. The project also packaged the tools in user-friendly code to be used internally by the Federal Aviation Administration (FAA). In addition, this project provided data and technical support to ASCENT projects 14 and 48. The enhanced tools help support the FAA in its strategic vision to reduce the significant health impacts of aviation emissions, by providing a rapid way of assessing the significant health impacts of any present or future aviation emissions scenario.
