Hochaufgelöste Erfassung der urbanen Feinstaubbelastung mittels Messnetz aus kostengünstigen Sensoren und numerischen Simulationen

The interdisciplinary „Smart Air Quality Net-work“ (SmartAQnet) project provides an overall system for recording, visualising and predicting the spatial distribution of air pollutant concentrations in urban atmospheres. Within more than three years SmartAQnet aimed to implement an inexpensive measurement network, which is transferable to other cities, and modelling systems (urban climate model PALM4U) for very finely resolved (spatially, temporally) air quality determination, initially in the model region of Augs-burg. The core component of the available system is a data management system at the project website www.smartaq.net/ en/dashboard/ that allows data of concentrations of PM₁₀, PM_2,5 and particle numbers of this network – including further air pollution and meteorological measurement as well as traffic counting and urban feature (buildings, streets) data – to be available for everybody. The multi-layered heterogeneous network implemented actually more than 100 middle-and low-cost-, partly new developed sensors. It was extended by mobile measurements (bicycles, stroller), unmanned aerial vehicles and remote sensing instruments for the three-dimensional recording of the distribution of air pollutants and meteorological parameters at an area of 10 x 10 km, so that some 100 million data sets are recorded. Here, citizen contribute by measurements with low-cost particulate sensors.
