MEGAPOLI 212520 understood. However, a complete quantitative picture of these interactions is clearly missing. Understanding and quantifying these missing links will be the focus of MEGAPOLI. Figure 1: Worldwide megacities (Source UN, 2002). B.1.3 Science and Technology methodology and associated work plan The MEGAPOLI project will be realised by 23 partners, representatives of leading research organizations in atmospheric pollution, meteorological and climate research, and organizations responsible for the urban air quality and population exposure forecast and control from 11 European countries. This breadth guarantees that the project can accomplish its ambitious objectives and tasks, ranging from the collection and analysis of state-of-the-art measurements to the continued development and application of complex numerical models to the distribution of results in a form directly usable by the end users and understandable by the public. The project also requires a very strong management and co-ordination due to its broad scientific basis. This will be accomplished through well-defined workpackages and its “management problem-solving approach”. Realisation of the objectives of the project as well as answering the key scientific questions (see Sect. 1.2) will be accomplished via nine separate but inter-linked Work Packages (WPs), which are shown schematically in Figure 3. The WPs are described below, first in terms of an overview of the workpackage concept and of the megacities in focus, and then in a more detailed description of the state-of-the-art and our plans to advance beyond this for each WP. B.1.3.1 Overall strategy and general description The first critical step in improving our understanding of how megacities impact air quality, atmospheric composition and climate on different scales is the development of high-quality inventories of the emissions of relevant gases and aerosols and their precursors, and determining how these are anticipated to change in the mid-term future, as well as how these change under various scenarios (e.g, movement of 10% of the population out of a megacity and into the surrounding countryside). This will form the key input to the remaining components of the study, 9

The connections and processes will be the focus of MEGAPOLI. In addition to the overall connections between megacities, air quality and climate, the figure shows the main feedbacks, ecosystem, health and weather impact pathways, and mitigation routes which will be investigated in MEGAPOLI. The relevant temporal and spatial scales are additionally included. and will also, through an understanding of the sensitivity of emissions of different compounds and from different sectors, form the basis for sensible approaches to mitigation strategies. This task will use as a starting point the corresponding emission inventories developed by local administrations for major urban areas. These will be improved when necessary, adjusted to the appropriate model scale and integrated into larger scale datasets for their use in regional and global scale atmospheric composition modelling. This approach will allow the exploitation of former investments and available information, and will build connections between local air quality management authorities and the air quality and climate research community. Emissions are the focus of WP1 in the project, and its links to the other aspects of the project as shown in Figure 3. WP2 is focusing on the megacity features (e.g. morphology), along with processes taking place in the urban canopy and boundary layer, which are responsible for the airborne transport and transformation of pollutants 10 Forcing Global ~10 4 km Climate 1 s - 1 hr Days - weeks Years-decades Connections Processes Impacts Mitigation Chemical Transformations Feedbacks Scales
