Abstract

Abstract Ultrafine particles (UFP) are moving more and more into the focus of public awareness thereby increasing the demand for measurements and indices together with assessment studies. Continuous measurements of UFP are performed only at three sites in Bavaria: Two of them are located in the regional background (Meteorological Observatory Hohenpeißenberg, Environmental Research Station Schneefernerhaus) far away from the direct influence of anthropogenic emission sources. The third one is situated in Augsburg on the campus of the University of applied sciences Augsburg – without strong local anthropogenic sources in the close surroundings (urban background). Therefore, the year-round load situation of UFP at characteristic urban places like main thoroughfares or industrial zones in Bavaria is largely unknown so far. Due to this lack of the spatial and temporal distribution within an urban area, UFP are now measured source-related, which means measurements with source attribution studies, in the city of Augsburg throughout the year (2017). First, the measurement data is subjected to quality assurance. Thereafter, analyses regarding the spatial as well as temporal distribution patterns together with meteorological influences are carried out and supplemented by relevant additional air pollutant measurements (PM2.5, PM10, nitrous gases, ozone) at the LÜB- (Lufthygienisches Landesüberwachungssystem Bayern) stations.
