is a major contributor to urban smog 1, 2, but how it occurs in cities is often puzzling 3. If the
growth rates of urban particles are similar to those found in cleaner environments (1–10
nanometres per hour), then existing understanding suggests that new urban particles should
be rapidly scavenged by the high concentration of pre-existing particles. Here we show,
