    ENV-e-CITY Environmentally Viable Electronic City
    (Environmental Communication in the Information Society - Proceedings of the 16th Conference, 2002) Moussiopoulos, Nicolas; Bøhler, Trond; Fedra, Kurt; Friedrich, Rainer; Karatzas, Kostas; Karppinen, Ari; Kraggerud, Per Haavard; Kukkonen, Jaakko; Larssen, Steinar; de Leeuw, Frank; Lohmeyer, Achim; Peinel, Gertraud; Pulles, Tinus; Reis, Stefan; Rose, Thomas; van der Hout, Dick
    The objective of project ENV-e-CITY is to develop an on-line application for environmental information related services. The e-content domain extends over four application areas: air emission, air quality, topography and meteorology. The application framework to be developed includes metadata structures for all application areas, export and import filters, interfaces and various e-content basic services. The user community of the platform envisaged consists of city authorities, consultants involved in environmental impact assessment studies and citizens desiring valid information on the state of the environment. An electronic market place for the e-content itself and the services is also envisaged.

    Environmental Services and Data Brokerage Portal: ENV-e-CITY in Action
    (The Information Society and Enlargement of the European Union, 2003) Moussiopoulos, Nicolas; Karatzas, Kostas; Endregard, Geir; Fedra, Kurt; Friedrich, Rainer; Johansen, Per Henrik; Kalognomou, Liana; Karppinen, Ari; Kraggerud, Per Haavard; Kukkonen, Jaakko; Larssen, Steinar; de Leeuw, Frank; Lohmeyer, Achim; Naneris, Chris; Nicklass, Daniel; Papaioannou, Giannis; Peinel, Gertraud; Pulles, Tinus; Reis, Stefan; Rose, Thomas; Sedlmayr, Martin; van den Hout, Dick
    ENV-e-CITY is a European Commission supported e-content project that aims to develop an internet-based service for environmental information related applications. The motivation of this project lies in the need of European cities to perform assessments for complying with the EU environmental legislation, as well as the requirement for efficient environmental impact assessments. The e-content domain considered extends over four environmental application areas: air emission, air quality, topography, and meteorology. The application framework includes meta-data structures for these domains, export and import filters, interfaces and typical e-content services. The user community of the platform envisaged consists of city authorities, consultants involved in environmental impact assessment studies as well as citizens desiring valid information on the state of the atmospheric environment. An initial set of electronic information services is currently under development and will be demonstrated on the basis of the various user categories.

    Short - Term PM10 Concentration Forecast Modelling in the MARQUIS-Service
    (Environmental Informatics and Systems Research, 2007) Lohmeyer, Achim; Duering, Ingo; Hoffmann, Tilo; Nicklaß, Daniel; Soergel, Christine
    The information system MARQUIS will provide to the public short-term air quality forecasts for selected areas in Europe. Basis for the forecasts are the current data gained by the air quality monitoring stations in the region and forecasts of the meteorological data. For the service concerning PM10, there is a need to do the forecast in the morning, forecasting the daily mean of the PM10 concentration for the current and the following days. The paper presents the examined methods for this short term PM10 forecast modelling at two open country monitoring stations in Germany on the basis of the results of EURAD (classical emission and dispersion modelling based on the area of Europe), Machine Learning, Multiple Linear Regression and Neural Networking. Advantages and disadvantages of the methods are discussed and some of the validations and of the future plans are presented. Additionally, the paper presents the status of the ProFet-System based operational modelling for three vehicle traffic dominated monitoring stations, using a Multiple Linear Regression model. The results of ProFet are foreseen for the real time information of the public and the triggering of measures for ad hoc reduction of vehicle traffic induced PM10 concentrations. Some of the validations and of the future plans are presented for ProFet as well.
