Black Carbon Aerosol Characteristics and Its Radiative Effect in Xuzhou City, China
Based on the measurement of the concentration and aerosol optical depth of black carbon aerosol during April 27, 2014 to August 1, 2016, in Xuzhou city, China, the black carbon aerosol temporal variability and its impact on the atmospheric radiative forcing were studied. The mean black carbon aerosol mass concentration during the measurement period was 2.278 ± 1.551 μg/m3 and demonstrated significantly seasonal variation with two peaks occurring in spring and winter. Simulating the radiative forcing of the black carbon aerosol by a radiative transfer model-6S code, it revealed that black carbon aerosol radiative forcing at the surface varies between about −0.37 to −15.24 W/m2, which represents a considerable amount of cooling to the surface.
