EcoSenseWeb is an integrated atmospheric dispersion and exposure assessment model which implements the Impact Pathway Approach
developed within ExternE.
It was designed for the analysis of single point sources (electricity and heat production) in Europe but it can also be used for analysis of multi emission sources in certain regions.
|Fig. 1: Impact Pathway Approach.|
EcoSense was developed to support the assessment of priority impacts resulting from the exposure to airborne pollutants, namely impacts on human health, crops, building materials and ecosystems.
The current version of EcoSenseWeb, covers the emission of ‘classical’ pollutants SO2, NOx, primary particulates, NMVOC, NH3, as well as some of the most important heavy metals.
It includes also damage assessment due to emission of greenhouse gases. Impacts of ‘classical’ pollutants are calculated on different spatial scales,
i.e. local (50 km around the emission source), regional (Europe-wide) and (northern) hemispheric scale.
The version EcoSenseWeb has a web-based user interface and was developed within the European Commission projects NEEDS and CASES.
The EcoSenseWeb and the calculation of external costs follow as far as possible the so called Impact Pathway Approach (IPA). The IPA, a bottom-up approach, is depicted in Figure 1.
The IPA starts with the emission of a pollutant at the location of the source into the environment; models its dispersion and chemical transformation in the different environmental media; identifies the exposure of the receptors and calculates the related impacts which then are aggregated to external costs.
|We are currently updating our software. The new version will inlcude new research findings such as an urban increment model, new concentration-response functions and the possibility to consider multisource scenarios. It will most likely be available in Spring 2017!|
