Momenteel werkt het RIVM aan een analyse van sensoren in Amsterdam in 2018. De eerste resultaten zijn voor commentaar in dit discussiestuk gevat. Alle commentaar is welkom. Het stuk is geschreven in het Engels, om het ook internationaal te kunnen delen.
During 2018 some twenty SDS-11 sensors located in Amsterdam provided data during at least part of the year. Some sensors provided data directly to RIVM, while others were part of the German “Luftdaten” project and data were downloaded from there. The results of the sensors have been compared to those of nearby reference measurements. After correction for the effects of humidity, there is a quite satisfactory agreement between the results of the sensors and of the reference measurements, for PM2.5 slightly more than for PM10, where the calibration proved to be more complex.
