Ice nucleation is one of the most uncertain microphysical processes, as it occurs in various ways and on many types of particles. To overcome this challenge, we present a heterogeneous ice nucleation study on deposition ice nucleation and i...
The contribution of new particle formation and subsequent growth to haze formation [0.03%]

Markku Kulmala et al.
We investigated the contribution of atmospheric new particle formation (NPF) and subsequent growth of the newly formed particles, characterized by high concentrations of fine particulate matter (PM2.5). In addition to having adverse effects...
What controls the observed size-dependency of the growth rates of sub-10 nm atmospheric particles? [0.03%]

Intense new particle formation events are regularly observed under highly polluted conditions, despite the high loss rates of nucleated clusters. Higher than expected cluster survival probability implies either ineffective scavenging by pre...
Observed coupling between air mass history, secondary growth of nucleation mode particles and aerosol pollution levels in Beijing [0.03%]
