Pollutant transport between a street canyon and a 3D urban array as a function of wind direction and roof height non-uniformity
Data Quality and Accuracy of Measurements
The measurement system was successfully tested by simpler well-known flow situations and the results of the concentration measurements for simpler street-canyon model AR-1 were successfully compared with the previous results of Soulhac et al. (2009). The total measurement error of the pollution fluxes was estimated to be less than 5% using ensemble statistics, taking into account the errors of velocity (1%), concentration measurements (4%) and the positioning error of the 3D traverse system (1%).
