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


EMeRGe scientific target

Main focus of research:

Local anthropogenic and natural emissions coupled with meteorology determine transport and transformation (T&T) of MPC outflows.

Dominant dispersion and transport patterns of MPC outflows

Dominant factors in the chemical transformation of MPC emissions

Relevance of MPC emissions for radiative forcing and climate change

Investigation of the regional and hemispheric impact of the outflow of major population centers (MPC) in Europe and Asia on atmospheric composition

Hypothesis:

Adequacy of chemical models for T&T of European and Asian MPCs outflows

Impact of topography and meteorology on the outflow

Overarching objective:

Impact of MPC emissions poorly understood and imprecisely quantified

Scientific approach

EMeRGe different levels of synergy


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

HALO - EMeRGe measurement campaigns

EMeRGe campaigns in Europe and East Asia are complementary and synergistic

Europe (July 2017)

Total 145 flight hours

Summer: Prevalence of quasi permanent weather systems promoting • Active photochemistry, smog

production, • convection, low precipitation • advection from Northern Europe

into the Mediterranean

EMeRGe campaigns in Europe and East Asia are complementary and synergistic

HALO - EMeRGe measurement campaigns

East Asia (April 2018)

Total 145 flight hours

Spring: Prevalence of storm & frontal systems:

• maximum Asian outflow over the Pacific

• transport of pollution into the free troposphere (warm conveyor belts)

Frequent and rapid transpacific transport Maximum biomass burning February to

April. Mixing MPC outflows with dust from
