| Zusammenfassung |
| Since 2007 more than half of the world’s population lives in an urban environment. Beside
many other challenges most large cities have problems with their air quality. Thus a growing
fraction of humans is exposed to e.g. high ozone and particulate matter concentrations, which
are known to be harmful to health. As they are emission hotspots, huge urban agglomerations
not only have local effects but globally influence the chemical air composition and with it the
climate.
Within the EU FP7 CityZen project a series of different scale models is employed in order
to analyze the impacts of air pollution hot spots on regional and global air quality including
potential future changes for various climate scenarios. A crucial part for the simulations are
the emission inventories used. Therefore a comparison of the RETRO inventory and the
new IPCC AR5 anthropogenic emissions with focus on the CityZen case study
regions has been performed, as a preparatory step for modelling work within CityZen.
Differences, especially in NOx, CO emissions and their emission ratio were analyzed and
evaluated. The new IPCC AR5 anthropogenic emission data were found to better reflect
spatial emission patterns and gradients of metropolitan areas and for this reason
to be suitable for global modelling studies of megacities’ air quality and climate
impact. |
