Short summary
Widely used formulae underestimate the atmospheric new particle formation (NPF) rate when intense NPF events are analyzed. This is caused by the underestimation or neglect of the coagulation scavenging effect. To address this issue, a new formula was theoretically derived. Aerosol down to ~ 1 nm was measured in Beijing and used together with data reported in the literature to test the new formula and others. Implications for NPF rates in various atmospheric environments are discussed.
