MDPI Air Near-field Fireworks Pollution Assessment Dataset

This deposit accompanies the paper "AETOS: Near-Field Urban Pollution Monitoring Using a Distributed Sensor Network and Backward–Forward Lagrangian Modeling: A Fireworks Case Study at Lake Union, Seattle". It contains the raw sensor measurements, regulatory and meteorological reference data, and the full Python processing and dispersion-modeling pipeline used to produce all results, tables, and figures in the manuscript.

Field campaign. On 4 July 2025, six AeroSpec low-cost particulate matter sensors were deployed within ~2 km of the Independence Day fireworks launch site over Lake Union (Seattle, WA, USA). All six nodes recorded at 1 Hz from 20:00 to 23:30 PDT. Five sensors (S1, S2, S3, S5, S6) were retained for primary analysis; S4 was excluded due to pre-event contamination from a nearby unrelated source and is included here for completeness with a quality-control flag. Deployment coordinates and per-sensor distances to the launch site are documented in the README.

Reference data. The deposit includes hourly PM2.5 and PM10 measurements from three southern EPA Air Quality System (AQS) regulatory stations (10th & Weller, Beacon Hill, Duwamish), hourly AQI from three northern Washington State Department of Ecology stations (Linden Ave N, NE 127th St, College Way N), and 5-minute METAR observations (wind speed, wind direction, temperature, cloud cover) from KSEA (Seattle-Tacoma International Airport).

Citation. If you use these data or code, please cite both this deposit and the accompanying paper.
