| Abstract | In the recent decade, the mobile measurement technology has been demonstrated to be an effective way to perform larger scale spatial evaluation of air quality for urban city compared to the conventional stationary one. However, it is difficult to perform mobile measurement of PM10 mass concentrations due to the principles of the instrument (e.g. TEOM) may not be applied properly on a moving platform. To overcome this problem, an approach was proposed here. In this study, continuous street level measurements of aerosol size distribution function were performed in the entire area of a small city, Macau, by utilizing a mobile monitoring platform equipped with Wide-Range Particle Spectrometer (WPS) for 7 consecutive days. In order to transform the measured distribution function into the total mass concentration, the mobile platform was parked near a fixed station equipped with TEOM to perform co-located measurements during the overnight period in these 7 days. The aerosol size distribution function obtained during the overnight period was further transformed to the total particle volume concentration. From the regression between the total particle volume concentrations from WPS and the PM10 mass concentrations directly measured by TEOM, the apparent density for PM10 was estimated to be 1.35g/cc in this study. Then, the PM10 mass concentrations in the mobile measurement route could be deduced from the WPS measurements with this estimated apparent density for assessment. It was found that the estimated PM10 mass concentrations in the monitoring route obtained from this method were generally consistent to those measured PM10 concentrations of the fixed monitoring stations located nearby the measurement route; hence confirming the workability of the present proposed approach. |
