Sitting on the Lima river valley in northern Portugal, Ponte de Lima sees vehicle traffic and agriculture across the river valley as the dominant local influence on air quality, while the surrounding Viana do Castelo terrain affects how pollutants disperse. Calm, still conditions tend to let levels build here more than in breezier weather, and the local topography around Ponte de Lima can trap emissions for longer stretches during stable atmospheric periods.
