Antrittsvorlesung: Understanding Earth: From Local to Global Scale Observations and Modeling Interpretation

Prof. Dr. Mihalis Vrekoussis, IUP, Universität Bremen

Since the beginning of the Anthropocene (coming from the combination of the Greek words "Anthropos-Άνθρωπος" meaning man and "Ceno-Καινό" meaning new), both the number of chemical species and the magnitude of their emissions have been increasing rapidly, being modified by human activities, such as fossil fuel combustion and land use change. The above emissions are often linked with direct and indirect effects on climate and air quality with adverse impact on human’s health. To assess the impact of current and future anthropogenic activities, in addition to the natural environmental changes, a thorough understanding of the surface fluxes, transport and transformation of atmospheric constituents is required. This information emanates from observations of trace species at various spatial scales from local to global, and their interpretation with state-of-the-art numerical models. Today, a number of studies will be presented highlighting the synergy between observations [in situ and remote-based, airborne-based with the use of unmanned aerial vehicles and global space-based] and modeling simulations [box (0D), chemical-transport (CTM), and inverse models (IM)]. Ultimately, the combination of the above leads to the understanding of various complex atmospheric processes which in turn, is an imperative for development and optimization of the needed tools for robust control strategies to mitigate emissions of trace gases.
