Abstract. Megacities and other major population centres (MPCs) worldwide are sources of air pollution, both locally as well downwind. The overall assessment prediction the impact MPC pollution on tropospheric chemistry challenging. present work provides an overview highlights a new contribution to understanding this issue based data analysis EMeRGe (Effect transport transformation pollutants Regional Global scales) international project. focuses atmospheric chemistry, dynamics, local...
Abstract. This article describes the volcanic effect of Mt Pinatubo eruption in June 1991 on ozone (O3) and methane (CH4) distribution stratosphere, as simulated with chemistry–climate model EMAC (ECHAM/MESSy Atmospheric Chemistry: ECHAM5, version 5.3.02; MESSy, 2.51). In this study, effects heating heterogeneous chemistry chemical composition, caused by aerosol, are separated. Global simulations over relevant period from 1989 to 1997 T42L90MA resolution specified dynamics interactive were...
Abstract. EMeRGe (Effect of Megacities on the transport and transformation pollutants Regional to Global scales) is an international project focusing atmospheric chemistry, dynamics local regional pollution originating in megacities other major population centres (MPCs). Airborne measurements, taking advantage long range capabilities HALO research platform (High Altitude Long aircraft, www.halo-spp.de), are a central part project. In order provide adequate set measurements at different...
Abstract. Emissions of land transport and anthropogenic non-traffic emissions (e.g. industry, households power generation) are significant sources nitrogen oxides, carbon monoxide volatile organic compounds (VOCs). These important precursors tropospheric ozone affect air quality. The contribution the emission sectors to cannot be measured directly but can only calculated using sophisticated atmospheric chemistry models. For this study we apply MECO(n) model system (MESSy-fied ECHAM COSMO...

Emissions of land transport and anthropogenic non-traffic emissions (e.g. industry, households power generation) are significant sources nitrogen oxides, carbon monoxide, volatile organic compounds. These important precursors tropospheric ozone affect air quality. The contribution emission sectors to cannot be mea- sured directly, but calculated with sophisticated models atmospheric chemistry only. For this study we apply a the MECO(n) model system (MESSy-fied ECHAM COSMO nested n...
<p>Comprehensive regional chemistry-climate or chemistry transport models are important tools to study the impact of emissions from major population centres (MPC) and/or investigate potential mitigation options for MPC emissions. Before such can be employed it is how well represent observed atmospheric conditions. This comparison helps not only in judging performance models, but allows test our understanding chemical and physical processes atmosphere. A prerequisite an...
<p>Non-traffic (i.e. households, industry, etc.) emissions and land transport are important anthropogenic precursors of tropospheric O3 affect the air quality contribute to global climate change. In order improve mitigate change, robust knowledge amount formed by different emission sources is required. This study investigates contributions sectors ground-level ozone budget in Europe Southeast Asia. For present we applied MECO(n) model system, which couples chemistry-climate...
