Abstract
The tandem monitoring system composed of Scanning Mobility Particle Sizer and Aerodynamic ParticleSizer (SMPS-APS) was simultaneously operated with other PM mass monitoring devices using β-ray absorptionmethod such as BAM 1020 at Seoul intensive monitoring site during over 3 months, 2010. The monitoringresults of SMPS-APS combination and β-ray absorption method show high correlation when the relativehumidity was between 40 % and 60 %. On the other hands, the correlation between two monitoring methodswas obviously low in high humidity due to the hygroscopic growth of particles. In addition, several Asian dustAD) and high PM episodes observed during the monitoring period seemed to make a difference to the monitoringresults. The SMPS-APS system underestimated the PM 10 mass concentration during AD periodsbecause the counting efficiency of APS decreases for the large particles (> 5 µm), whereas the overestimatingthe PM 2.5 mass for high PM episodes due to hygroscopic growth of fine aerosol and recounting the small particlesin the boundary size range of SMPS and APS was observed.
