... The CWT method was further applied to determine the relative contribution of PM2.5 potential sources in the CCUA [41]. To address the uncertainty of fewer PM2.5 trajectories in a certain grid, the weighting factor should be multiplied with the PSCF value (WPSCF) and CWT value (WCWT) to reduce its uncertainty [42]. More details of the PSCF and CWT method are available in Zhang et al. [43]. ...

... Scholars have conducted extensive and in-depth studies on the distribution and propagation process of air pollutants and their impact on population health [12][13][14], including the effect of meteorological conditions on the distribution of air pollutants [15,16] and the spatial correlation between air pollution and public health [17,18]. However, most studies have focused on large cities such as Shanghai, Nanjing, Hangzhou, and Hefei [19,20]. Because of its unique geographical environment, in addition to its inland cities, there are many coastal cities in the YRD region. ...
