Measurement report: Three years of size-resolved eddy-covariance particle number flux measurements in an urban environment
Abstract < D p < F TNC = 0.86 × 8 m- 2 - 1 D p < F UFP = 0. 83 × 8 m- 2 - 1 F TNC F UFP - - F UFP - - F UFP) from the second to the third year. The annual variation might be due to different reasons such as the variation of flux footprints in the individual years, a slight reduction of traffic intensity in the third year, or a progressive transition of the vehicle fleet towards a higher share of low-emission standards or electric drive. Size-resolved measurements illustrated events of bidirectional fluxes, i.e. simultaneous emission and deposition fluxes within the size spectrum, which occurred more often in spring, late summer, and autumn than in winter. Multi-year observations of size-resolved particle fluxes proved to be important for a deeper understanding of particle exchange processes with the urban surface and the pronounced influence of traffic at this urban site.
