New particle formation (NPF) impacts both air quality and climate. Recent breakthroughs in measurement techniques have revealed that NPF proceeds via cluster formation, and several mechanisms are likely to occur in the atmosphere.
Most data on NPF has been obtained at fixed atmospheric supersites with mass spectrometric tools. Such sites are rare, and they cover only a few land use types; therefore, models of NPF are likely biased towards the supersite environments. We propose a research project that will extend our knowledge of clusters and NPF to new environmental zones, such as coasts, the Arctic, farmlands, and traffic.
We will perform expeditions using a mobile laboratory, fitted with constant measurement suite of two mass spectrometers, cluster-sized aerosol detectors, and gas detectors. We will extend such measurements to new, unprobed areas and provide quantitative intercomparisons between environments, and produce an unprecedented open dataset of atmospheric clusters.
