Project Description

This purpose of this project is to evaluate the contribution of aviation sources to ultrafine particulate matter (UFP) and other air pollutant concentrations in communities surrounding an airport. In this study, UFP and other pollutants are measured at high temporal resolution at multiple sites concurrently, with sites selected specifically for the purpose of aircraft source attribution. Detailed flight activity tracks and meteorological data are used as predictors of measured concentrations, using statistical methods that allow for the aviation signal to be separated from other sources of air pollution.

Monitoring sites were chosen directly underneath a major arrival flight path to Boston Logan International Airport, as well as at sites at varying lateral distances from the flight path, to allow for a formal evaluation of the magnitude of aviation contributions over a large spatial domain.

In addition to the ongoing field campaign and related statistical analyses, researchers on Project 18 work on collaborative efforts with Projects 19 and 20 to model the public health impacts of aviation emissions at national and global scales.
