Leipzig-IfT is a research station operated by the Leibniz Institute for Tropospheric Research (IfT) Leipzig. The station is situated on the roof of IfT’s institute building. Leipzig is a medium-sized city in Saxony with approximately 500 000 inhabitants. Aerosol particles are sampled at a height of 16 m above the ground. Highly-trafficked roads touch the area only at distances of at least 100 m. The location has been identified as representative for urban background conditions in Leipzig (Costabile et al., 2009). In 2011 the station can look back on a 14-year record of urban particle number size distributions (Wehner and Wiedensohler, 2003). PM10 measurements are absent at Leipzig-IfT; therefore, corresponding data from the urban background station Leipzig-West, part of the state air quality monitoring network in Saxony, appear in some graphs and tables of this paper.
