입경 분포 원인 분석 및 PM2.5 밀도 추정 -Part II Source Analysis of Size Distribution and Density Estimation in PM2.5 -Part II
Abstract To characterize the features of particle apparent density, continuous measurements of particle number size distributions from optical particle sizer (OPS) and 24 hr integrated particle mass concentrations from filter based sampler were conducted at the National institute of environmental research NamBu Supersite (NNBS, 35.22°N, 126.84°E) in Gwangju for 16 days from Nov. 4 in 2014. Source apportionment model was carried out by applying Positive Matrix Factorization (PMF) to particle size distribution data. Three different distributions related to primary and secondary sources were investigated by the diurnal patterns of identified factors. Density estimated by gaussian model has been calculated as 1.69 g/cm3 with 95% confidence bounds (1.57~1.81 g/cm3).
Key words PMF, OPS, Size distribution, Density
