Table 2. The correlations among the AOD, Fine-Mode (aerodynamic diameter (Dp) < 1 μm)) AOD, CF, CER from the NP to the interior China in the dry season (Oct.–May) and rainy season (June–Sep.) during 2000–2012. All the correlation coefficients are tested using the Pearson correlation test, the single asterisk is for P < 0.05, and the double asterisk is on behalf of P < 0.01.
