Short summary

In cloud condensation nuclei (CCN) measurements, the supersaturation scan is often time-consuming and limits the temporal resolution of CCN measurements. Here we present a new concept, termed the broad supersaturation scanning (BS2) method, in which a range of supersaturation is simultaneously scanned, resulting in fast measurements of CCN activity.
