  • Technical Abstract

    Deliverable Number D05.02
    Title of Deliverable ECOSIM user documentation

    ECOSIM will be a support system to investigate and forecast pollution levels in urban areas. By allowing the effects of industrial developments or new roads to be quickly and easily examined, public authorities can use ECOSIM to ensure that their urban plans fully consider environmental impacts. ECOSIM will also be able to forecast pollution levels - typically over the next 24 hours.

    ECOSIM will be based on sophisticated computer models such as those which allow ozone levels to be calculated from road traffic emissions. It combines these models with up-to-date measurements of current meteorological conditions and pollution by linking directly into local databases and pollution measurement stations. ECOSIM also links the various domains such as surface water, coastal water and air to ensure that as complete a picture as possible can be predicted of environmental conditions.

    ECOSIM makes use of very high performance computers whenever it needs to and uses the latest methods in handling maps and similar data to ensure that its results can be easily translated into practical measures for pollution control.

    Executive Summary

    Deliverable Number D05.02
    Title of Deliverable ECOSIM user documentation

    This document, the user documentation, will enable an end-user of the ECOSIM system to decide if the application of ECOSIM is useful for solving his problems and will enable him to use the ECOSIM system through detailed guidance.

    This first issue gives a principle overview of the system. It describes the main model parts, its theoretical background, its capabilities and requirements. In addition, it introduces the main server and explains his basic features.

    The document will be regularly updated to cover all new project developments. Especially data formats, model options and concrete operating instructions will be added in the next issues.

    The document gives an introduction and shows the principle simulation system design of ECOSIM (air pollution modelling only). The ECOSIM main server is described which includes a Geographical Information System (GIS) and a data base, enables networking and remote control of simulation runs. It connects monitoring information with model data for initialisation, background information or validation purposes. The design of the models and the theoretical description is given. It includes opportunities of ozone forecasting with different complexity of the models. The document presents the set of input data which is required for the use of ECOSIM. The main data set consists of a digital elevation map, a land use map, an emission inventory and initial and boundary values.
