Short summary
This study investigated the seasonal and diurnal variability of fine aerosol composition in two forest ecosystems in North and South China. Carbonaceous/nitrogenous compound concentrations were higher in winter than summer at both sites. The forest fine aerosols in high latitude exhibited significantly greater influence from fossil fuel combustion compared to that in low latitude.
