    Aircraft arrivals analysis: Progress update

    This January 2018 progress update from ESA presents an analysis of aircraft arrivals at Seattle-Tacoma International Airport (SEA), examining whether notable changes occurred between 2013, 2015, and 2017. The study uses radar flight track data from July and December of each year to compare fleet mix, runway usage, and aircraft altitudes at six nautical miles from the airport. Key questions addressed include whether arrival numbers increased, whether traffic flow patterns shifted between north and south flow, and whether arriving aircraft were flying at different altitudes over the study period.

    Ultrafine particles near airports

    Researchers from the University of Washington School of Public Health were commissioned by Washington State to study ultrafine particle air pollution near Sea-Tac Airport, the busiest international airport in the state. The study, presented in November 2017, required measuring ultrafine particulate matter within ten miles of the airport along flight paths, distinguishing aircraft emissions from other pollution sources, and comparing affected areas to unaffected ones. Findings and recommendations on whether to proceed with a second phase of research were due to the state legislature by December 1, 2019.
