Notes: values in the upper right represent correlations during winter time (Oct–Mar); values in the lower left represent correlations during summer time (Apr–Sep). PMF stands for the Positive Matrix Factorization; CMB stands for the Chemical Mass Balance method; GV stands for gasoline vehicles; DV stands for diesel vehicles; mob stands for mobile sources=GV+DV.
