CurieuzeNeuzen: monitoring air quality together with 20.000 citizens

Traffic sources contribute a large portion of the ambient nitrogen dioxide, particulate matter and ozone concentrations, the three ambient air pollutants with the largest impact on human health in Europe (EEA, 2018). High spatial resolution air quality data capturing the high spatial variability of this traffic related pollution are necessary in order to inform policy. The approach of environmental protection agencies around the world to measure using expensive monitoring stations allows monitoring in high temporal, but not spatial, resolution (Snyder et al., 2013).
