Presenter: Tuija Jokinen, University of Helsinki.
Tuesday’s Science Talk will introduce aerosol research from the MOSAiC expedition & Ny-Ålesund done by the Polar and Arctic atmospheric research (PANDA) group, University of Helsinki. We study new particle formation, which is a process where tiny particles are formed out of vapour molecules in the atmosphere. Those newly formed particles – or molecular clusters with sizes around 1-3 nanometers – can grow to sizes of cloud condensation nuclei (> 50 nanometers) and influence the optical properties, lifetime and precipitation of clouds, thereby connecting new particle formation to Earth’s radiative balance and climate.
