Sitting on the forested plain north of Helsinki, Nurmijärvi sees vehicle traffic and Helsinki commuter routes as the dominant local influence on air quality, while the surrounding Uusimaa terrain affects how pollutants disperse. Calm, still conditions tend to let levels build here more than in breezier weather, and the local topography around Nurmijärvi can trap emissions for longer stretches during stable atmospheric periods.
