The formation of cloud condensation nuclei (CCN) via new particle formation (NPF) is believed to account for around 50% of all CCN in the atmosphere. NPF starts with the formation of small clusters of gas molecules, which then grow by collision with other clusters and condensation of gasses onto the clusters. However, the mechanism of their formation is still poorly understood. It has been established that the polar regions are warming two to three times faster than other parts of the globe. This warming is a result of, and will lead to changes in, aerosol precursor emissions and formation rates above the polar regions.
