Transport of black carbon aerosols from non-local sources: A case study in Shanghai

- Black carbon (BC) and meteorological data from Jan 2008 to Dec 2012 were measured in Shanghai.
- BC aerosol mass carried by winds of varying directions from non-local sources was estimated.
- Relationships between BC aerosols and wind speed were analyzed.
- Total BC mass contributed by non-local sources was 6404.05 t per year in Shanghai.
- BC mass transported into Shanghai in winter was about 35% of the whole year.
