The airQmap below has been created by Leuven2030. The map shows the average BC (Black Carbon) concentrations in Leuven during the period May 11 2016 – June 19 2016. Two maps are available:
This map has been realized based on mobile BC measurements collected by volunteers on a bicycle. The ‘weekend’ map shows the aggregated results of 19 measurement runs on 11 different days over the same track of 14 km. The ‘working days’ map shows the aggregated result of 27 measurement runs on 18 different working days over the same track. Each measurement run has started at the city office of Leuven and the biking direction has always been clockwise. Repeated measurements are needed to obtain a representative image of the air quality differences in the city. Previous studies of VITO indicated that at least 25 repetitions are required to obtain acceptable results. During the weekends, the number of repetitions was somewhat lower but still acceptable since less variation in air quality is present at that time.
