Research data supporting “PM2.5 source apportionment using organic marker-based CMB modeling: influence of inorganic markers and sensitivity to source profile”

Organic components (including 11 n-alkanes, 17 PAHs, 3 hopanes, 2 fatty acids, levoglucosan and cholesterol) in ambient PM2.5 samples were detected. There were 64 PM2.5 samples collected from January to December in 2018 in a Chinese megacity.
