Aerosol processes in atmosphere during changing climate conditions

The study of new particle formation (NPF) processes is crucial for advancing our understanding of anthropogenic impacts on atmospheric aerosol distribution and resulting climate forcing. In this work, we study the fundamental mechanisms behind NPF and explore how climate change has altered the atmosphere’s capacity to generate new particles. Our investigation combines historical nanoparticle data, cutting-edge laboratory experiments, and extensive station networks across Estonia (from island Vilsandi to Lake Peipus) and even extends into Finland, reaching up to Lapland. Investigations are linked to the Estonian Science Infrastructure Roadmap Project “Estonian Environmental Observatory” and European CERN CLOUD experiment.
