Zusammenfassung
Emission inventories require the management, documentation and interrelation of large amount of heterogeneous data in a user-controlled logic. emikat.at is a system that supports those who establish emission inventories and work with it.
emikat.at consists of a data administration server and a user interface residing on the users’ PC’s (client). At the server database all data is administered specifically for different clients and different versions. Access is limited to authorized clients and their users. Through the user interface, users have the possibility to add, edit and delete data as wells as to define alternate scenarios and to calculate model results. emikat.at derives emissions for the smallest available administrative units, i.e. „census tracts“. In each census tract, emissions are calculated according to the specific properties of emission sources, organized according to business sectors (NACE-system), emission source categories (SNAP-system), as well as according to input materials, fuel types and transformation processes. Emissions from line sources (road traffic) are directly associated to the major roads of a census tract. Emissions can also be calculated on the basis of a 100x100 m raster grid; in that case, land use within a census tract is considered for the spatial allocation of emissions. Results that have a defined spatial reference (such as census tracts, communities, counties, raster cells) can also be visualized as maps.
The system was applied to calculate the emissions for the reference year 2003 for the city of Vienna along with two „what-if“-scenarios of this reference year. This paper includes a few illustrative results from the Vienna case study.
