Air Quality Exposure Modeling System
Research area and project description:
The project lies in the research area of local scale ambient air quality modelling and monitoring.
The aim of the project is the development of a novel model system for air quality at address level and personal route exposure based on the Operational Street Pollution Model (OSPM). The system should be specifically developed, tested and implemented for Denmark as prototype due to the excellent input data quality by well-maintained high-quality national registers and databases on traffic, emissions, buildings, personal address history and health. However it is required that the modelling system will be transferable and applicable in other locations as well, especially tropical and sub-tropical regions. A test of the system for Doha/Qatar and a comparison to other similar systems and measurements should be performed.
The development of such a system is very timely due to the growing evidence for links between air pollution exposure and various types health outcomes and new methods and research are urgently needed to address air pollution exposure in a more comprehensive and efficient way.
The project covers both aspects of further development of the atmospheric dispersion and chemical reaction part of the model as well as the generation of the model input by means of geographic information system (GIS). Furthermore a validation of the new developed system should be performed based on measurements.
Since OSPM has been developed for typical northern European conditions, it is necessary to further develop and test the model for conditions found in Qatar, e.g. influence on specific flow-patterns due to much wider streets with single high buildings or influence on chemical reaction due to higher temperatures and solar insulation.
When applied to large number of addresses the input to OSPM is typically generated from larger geographic datasets or maps on street- and building geometry and traffic information, e.g. via the AirGIS system. The AirGIS has to be adopted and further developed to reflect the changed OSPM input requirements, e.g. the recently developed extension in OSPM to account for inhomogeneous distribution of the vehicle emissions across the street canyon.
The present Danish OSPM /AirGIS modelling system, that forms a starting point for the project, has mostly focus on emissions from vehicle traffic (line sources). The possible demand and available options of extending the system to include other source sectors (point and area sources) should be investigated.
