WebJan 1, 2015 · 2.2. Potential source contribution function (PSCF) To estimate the potential source locations for long–range transported aerosols, PSCF was calculated using the isentropic backward trajectories (Ashbaugh et al., 1985; Hwang and Hopke, 2007).Backward trajectories of air mass originating from the COSC station when PM 2.5 concentrations … Webyij, the PSCF values were multiplied by an arbitrary weight function Wij to bet-ter reflect the uncertainty in the values for these cells [3], [4], [11], [12]. The weighting function reduced the PSCF values when the total number of the end-points in a particular cell was less than about three times the average value of the end points for each cell.
