1 Effect of Megacities on the transport and transformation of pollutants on the Regional and Global scale (EMeRGe) Scientific target and project structure J. P. Burrows M. D. Andrés Hernández University of Bremen on behalf of the the EMeRGe team HALO- EMeRGe EMeRGe- International

2 EMeRGe scientific target Impact of MPC emissions poorly understood and imprecisely Overarching objective: quantified Investigation of the regional and hemispheric impact of the outflow of major population centers (MPC) in Europe and Asia on atmospheric composition Hypothesis: Local anthropogenic and natural emissions coupled with meteorology determine transport and transformation (T&T) of MPC outflows. Main focus of research: Dominant dispersion and transport patterns of MPC outflows Impact of topography and meteorology on the outflow Dominant factors in the chemical transformation of MPC emissions Adequacy of chemical models for T&T of European and Asian MPCs outflows Relevance of MPC emissions for radiative forcing and climate change

3 EMeRGe different levels of synergy Physical and chemical processes Transport and transformation MPCs outflows Europe (summer 2017) and Asia (spring 2018) Scientific approach data sources Airborne-HALO measurements Satellite products Ground based data Modelling Payload diversity and adequacy Universities and research institutions in situ and remote Trace gases and aerosols

4 EMeRGe overall scientific concept EMeRGe is an innovative research project exploiting the new platform HALO for pollution EMeRGe aims to test our understanding of the transport and transformation of emissions from MPCs in European summer and Asia spring, building on the heritage of previous campaigns. EMeRGe focuses on the production of ozone and aerosol and their precursors. EMeRGe has a synergetic payload of instruments for HALO EMeRGe utilises synergistically satellite and ground based data products to constrain our knowledge of the MPC source regions for the outflow targeted for HALO flights. EMeRGe investigates our understanding of transport and transformation processes by comparison of the measurements with state of the art models
