Short summary

Based on long-term measurements, we discovered that the collision of H₂SO₄–amine clusters is the governing mechanism that initializes fast new particle formation in the polluted atmospheric environment of urban Beijing. The mechanism and the governing factors for H₂SO₄–amine nucleation in the polluted atmosphere are quantitatively investigated in this study.
