Abstract: This contribution presents a dynamical downscaling process from global climate simulations to urban scale with 50 m spatial resolution. The final objective is to show how urban meteorological and air pollution responds to different global climate conditions and how human health could be affected. We have used the mesoscale model WRF-Chem (NOAA, US) to produce information covering all Europe with 25 km spatial resolution and two nested domains over Madrid, London and Milan. Finally, detailed simulations are performed using the MICROSYS-CFD model. Year 2011 is used as reference year and 2030, 2050 and 2100 for future under two RCP scenarios of the IPCC, 4.5 and 8.5. For evaluation we make a comparison between results of a simulation for present situation and observations showing acceptable agreement with measurements. The results are analysed with climate and health indicators for mortality and morbidity, using epidemiological studies to fix the exposure-response functions.
