English abstract:
A simple approach to modeling the radiation exchange in complex urban environments using readily available geospatial information and weather station measurements could serve as a useful tool for studying site specific impacts regarding the Urban Heat Island (UHI) and pedestrian thermal comfort. This research presents a solar radiation model that is based on a simplification of the SOLWEIG model, It was developed for the open source Geographic Information System (GIS) software QUANTUM GIS and utilizes open government data from the City of Vienna. In an effort to validate this model as well as compare it to the SOLWEIG model, measurements of global irradiance were taken throughout an urban setting and compared with the modeling results. The values derived form the models corresponded well with measured values. Furthermore, despite being a simplification of the SOLWEIG model the approahc taken in this study showed better overall fit to measured values. This is likely the result of using a greater temperoral resolution.
