CERA project information for TransClim

Road traffic emissions of nitrogen oxides (NOx), carbon monooxide (CO) and volatile organic compounds (VOC) influence the concentration of ozone (O3) and methane (CH4) in the atmosphere. These greenhouse gases contribute to anthropogenic global warming. Mitigation strategies for road traffic can help to lower the impact of road traffic emissions on climate. In order to assess these mitigation stratgies, we developed a new chemistry-climate response model called TransClim (Modelling the effect of surface Transportation on Climate).
The response model bases on look-up tables. They are generated by a set of emission variation simulations performed with the global chemistry-climate model EMAC (ECHAM5 v5.3.02, MESSy v2.53.0). Road traffic emissions are divided into eleven emission regions. In each emission region, road traffic emissions on NOx, CO and VOC are changed and the resulting climate effect is utilized by TransClim.
