The environmental climate changes in the next decades include the exceedance of critical levels that cause changes in the weather patterns, extreme events, modifications of marine circulations, high levels of atmospheric pollutants, etc. The anthropogenic activities causing air pollution provoke feedback processes (both positive and negatives) in regional and global climatic systems, and therefore they should be assessed in an integrated framework. We propose the development and application of high-resolution three-dimensional global circulation models (GCMs) combined with other regional/global models and their coupling with atmosphere-ocean models in order to analyze the climatic system of Earth at a global and regional scale. The main milestone is the research of climatic sensitivity, including the integrated quantification of air quality forcing (gaseous and aerosol pollutants) in climate change on a global scale, and, especially, applied to high-resolution scale in problematic areas. We intend to establish the links between the control of atmospheric pollution, climate feedbacks, transboundary and intercontinental transport of air pollutants and mitigation of climate change. The development of techniques to infer the global properties from satellite data, which can provide fundamental climate data for evaluating and validating the model is also necessary in this framework. With the allocation of computational resources and processor hours in DEISA framework we will be able to determine with high resolution the impacts of climate change and air quality in future scenarios (e.g. for a period between 2000-2100).
