2025-10-31SeaTac Permanent Noise Monitors with HAWKZ8 final approach
A map of the Seattle-Tacoma area showing numbered noise monitoring station locations (numbered 1, 15–23, 25, 28) clustered around Seattle-Tacoma International Airport (SeaTac) and extending south through Des Moines, Federal Way, and toward Milton/Fife. The stations appear to track aircraft noise corridors along what is likely the primary north-south flight path, with a dark vertical line indicating the runway centerline or flight track. -

2025-10-03Urban Ultrafine Particles – Advisory Group Meeting
The University of Washington held an Advisory Group Meeting on October 3, 2025, focused on urban ultrafine particles (nano-particles) and their sources, including aviation-related emissions near areas like Sea-Tac Airport. The meeting aimed to foster dialogue, address knowledge gaps from the MOV-UP study, identify priority research questions, and guide scientific research on air quality monitoring. Advisors were asked to provide feedback on study design and methodology, with a time commitment including annual meetings and optional review of study outputs. -
2025-10-01Impacts of Aviation Emissions on Air Quality Near Hanscom Field, Bedford, Massachusetts – Results of a Two-Season Monitoring Campaign
A comprehensive study measuring ultrafine particles, lead, and other air pollutants from aviation emissions at Hanscom Field across four surrounding Massachusetts towns. The study found that UFP concentrations were up to two-fold higher at downwind sites and often exceeded WHO guidelines, with the highest impacts in Bedford and Lexington. -
2025-09-15SMPS Particle Bin Counts and Geometric Mean at SeaTac North
This contour plot displays Scanning Mobility Particle Sizer (SMPS) particle bin counts (log10 scale, 2.6–5.0) by particle size (5–382 nm) and local PST time (08:31–12:54) at the SeaTac North monitoring station on September 15, 2025. Brown diamond markers indicate the geometric mean particle diameter over time, generally ranging between approximately 15–30 nm. The chart was generated at 13:08:16 local time on 2025-09-15, with last UTC data at 19:54:26. -
