Additionally, for selected rainfall-runoff events, the following data were produced: total suspended solids concentrations and their particle size distribution (<63 µm: fine particles; >63 µm: coarse fraction), their elemental composition and organic content. The online monitoring data covers January 2018 - August 2022, whereas the sampled data were collected during September 2018 - 2021. These data are optimal for exploring flush dynamics, transport patterns of particles and particle-bound pollutants, and for developing and validating particle transport formulations in urban drainage models. This will allow a better identification of stormwater treatment and management strategies to effectively address different pollutant flushes, to support regulatory decision-making, and to minimise the impact of stormwater discharges on the receiving water bodies.Attribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/43Monitoring data to explore particle size distribution and elemental composition in a stormwater outlet from a German urban catchment
