Short summary

We studied supermicron aerosol particles (PM_1–10) for 12 years at a Finnish boreal forest by subtracting PM₁ from total measurements. This allowed us to examine their optical and mass properties, seasonal patterns and events like pollen and dust. We also measured particles >10 µm using filters, which are missed by optical instruments. These large particles significantly influence light scattering.
