The objectives of the DECAIR project are to improve urban air quality models by providing them with high quality input data derived from Earth Observation (EO). A demonstrator, able to manage and to automatic ally converts EO data into air quality model input data will be designed. It will be applied for the operational forecast of air pollution at Berlin and Madrid. The project identifies two levels of customers: scientists from companies and research institutions (henceforth, called model-users), who need input data for their simulation models (meteorological, topographic and emission data), and end-users (local authorities, health, traffic, decision makers) who need atmospheric and air quality models for scenario analysis and forecast on European urban areas. The air quality models used to perform these tasks can be considerably enhanced if provided with high quality input data. Increasing data spatial resolution, freshness and availability can do achieving this. The project identifies the model data that can be fruitfully supplied by EO. This will be done by using commercial solutions if available, or build on recent advances on EO data processing. Research tasks are foreseen to estimate model data that might be provided by EO. An additional key aspect of the project is to define a proper data management structure to improve and facilitate the use of EO satellite images. A common DECAIR database conceptual model will be defined to accommodate the various needs of general model-users, e.g. not limited to the users that take part in the project. The use of a common pivot database between model-users and EO information sources enables to deal with the various semantic and physicalheterogeneity aspects of the information sources. Thus, model users will have a uniform and global view of the data input data that can be derived from the EO sources.
DECAIR will build on concepts and techniques already developed and evaluated to:(i) refresh the database and (ii) define an universal access service to DECAIR's customers, based on WWW and internet communication networks. The definition of this data management structure will be done according to most recent studies, and should enable the use of the DECAIR approach to other application sites, different modelling scales and finally different environmental application.
