Short summary

Home heating is the major driver of air pollution across Europe, yet pollution trends and mitigation responses remain limited. PM₁ observations from 2016–2023 in a temperate European city influenced by continental pollution reveal changing sources and composition. Major pollution contributors were identified, shaping clear seasonal patterns. Air quality has improved with reduced heating emissions and regional precursors reductions, while secondary organic aerosols show increasing importance.
