Unravelling causes and tackling impacts of air pollution using multidisciplinary methods — •Mihalis Vrekoussis — Laboratory for Modeling and Observation of the Earth System (LAMOS), Institute of Environmental Physics (IUP), University of Bremen, Bremen, Germany — Center for Marine Environmental Sciences (MARUM), University of Bremen, Bremen, Germany — Energy, Environment and Water Research Centre, The Cyprus Institute (CyI), Nicosia, Cyprus

The nearly exponential increase of the world's population is associated with the over-exploitation of natural resources, unprecedented industrial growth, and land use change. These intensified human activities modify the number and amount of chemical species introduced into the Earth's atmosphere that, in turn, influence climate, air quality and human health. To assess these impacts, we need to improve our understanding of surface fluxes, transport, and transformation of atmospheric constituents linked to past, present and future anthropogenic activities, in addition to the natural environmental changes. An important step in addressing the latter emanates from a multi-disciplinary approach combining observations of trace species at various spatial scales, from local to global, with state-of-the-art numerical models. Herewith, selected synergistic studies will be presented, scrutinizing in situ, airborne, and space-based observations as well as numerical simulations. This approach is an imperative for development and optimization of the needed tools for robust control strategies to mitigate emissions of trace gases.
