New particle formation leads to enhanced cloud condensation nuclei concentrations at Antarctic Peninsula
Few studies have investigated the impact of new particle formation (NPF) on cloud condensation nuclei (CCN) in remote Antarctica, and none has elucidated the relationship between NPF and CCN production. To address that knowledge gap, we continuously measured the number size distribution of 2.5–300 n...
