“…Contributions from foreign sources were significant only at background sites, in particular at Zhuzhang in spring, which reflects the transport of biomass burning aerosols from Southeast Asia. Chinese biomass burning emissions have distinct seasonal patterns (Duncan et al, 2003;Song et al, 2010;Huang et al, 2012), but they have limited impacts at the seven rural sites as simulated by the model. The simulated EC concentrations at all seven rural sites were almost entirely due to Chinese anthropogenic residential and non-residential emissions.…”

“…We used the inventory developed by Streets et al (2003b) for the sake of completeness in the present study. A very recent study by Huang et al (2012) provided new emission estimates for the in-field crop residue burning in China, and we will explore the use of that inventory in a future study. However, as will be shown in Sect.…”

Abstract. We simulated elemental carbon (EC) and organic carbon (OC) aerosols in China and compared model results to surface measurements at Chinese rural and background sites, with the goal of deriving "top-down" emission estimates of EC and OC, as well as better quantifying the secondary sources of OC. We included in the model state-of-the-science Chinese "bottom-up" emission inventories for EC (1.92 TgC yr −1 ) and OC (3.95 TgC yr −1 ), as well as updated secondary OC formation pathways. The average simulated annual mean EC concentration at rural and background sites was 1.1 µgC m −3 , 56 % lower than the observed 2.5 µgC m −3 . The average simulated annual mean OC concentration at rural and background sites was 3.4 µgC m −3 , 76 % lower than the observed 14 µgC m −3 . Multiple regression to fit surface monthly mean EC observations at rural and background sites yielded the best estimate of Chinese EC source of 3.05 ± 0.78 TgC yr −1 . Based on the topdown EC emission estimate and observed seasonal primary OC/EC ratios, we estimated Chinese OC emissions to be 6.67 ± 1.30 TgC yr −1 . Using these top-down estimates, the simulated average annual mean EC concentration at rural and background sites was significantly improved to 1.9 µgC m −3 . However, the model still significantly underestimated observed OC in all seasons (simulated average annual mean OC at rural and background sites was 5.4 µgC m −3 ), with little skill in capturing the spatiotemporal variability. Secondary formation accounts for 21 % of Chinese annual mean surface OC in the model, with isoprene being the most important precursor. In summer, as high as 62 % of the observed surface OC may be due to secondary formation in eastern China. Our analysis points to four shortcomings in the current bottom-up inventories of Chinese carbonaceous aerosols: (1) the anthropogenic source is underestimated on a national scale, particularly for OC; (2) the spatiotemporal distributions of emissions are misrepresented; (3) there is a missing source in western China, likely associated with the use of biofuels or other low-quality fuels for heating; and (4) sources in fall are not well represented, either because the seasonal shifting of Published by Copernicus Publications on behalf of the European Geosciences Union. T.-M. Fu et al.: Carbonaceous aerosols in Chinaemissions and/or secondary formation are poorly captured or because specific fall emission events are missing. In addition, secondary production of OC in China is severely underestimated. More regional measurements with better spatiotemporal coverage are needed to resolve these shortcomings.

• Collected PM 2.5 samples at TI were analyzed for OC and EC.• High winter EC concentrations were mainly from northwest source region.• High spring OC levels were largely from biofuel burning in Shandong Peninsula.• Agricultural field burning in the peninsula was a major source of summer OC and EC. a b s t r a c t a r t i c l e i n f o , which contributed 8% and 4% of PM 2.5 mass concentrations, respectively. High EC concentrations occurred in winter, contributed mainly by EC outflow from the northwest source region, while high OC concentrations were found during spring, attributed largely to biofuel burning in the Shandong Peninsula, and short distance and favorable transport from the peninsula to the TI. Agricultural waste open burning in the peninsula caused the largest variability of OC concentration in summer. Eliminating agricultural field burning in the peninsula can reduce at least one-third of concentration levels and half of northward transport fluxes of OC and EC in Bohai Rim in summer.

“…Wheat is the most widely cultivated crop in East China (e.g., Hebei, Henan, Shandong, and Anhui provinces), and the wheat is sown around midOctober and reaped at the end of May or the beginning of June. In June, after the harvest, the straw of the wheat is burned (Huang et al, 2012). This opposite trend may be attributable to the crop residue fires set in June in East China.…”

Active fire products from Moderate Resolution Imag ing Spectroradiometer (MODIS) satellite observation during the 16 years from 20002015 were analyzed to estimate spatial and temporal variations of wild land fires over East Asia (region of interest: 20°N 55°N, 100°E150°E). GLOBCOVER 2009 land cover data were also used to investigate the trend in wild fire occurrence with respect to each land cover type. Statistical analysis showed that the highest number of wildland fires occurred in the evergreen and veg etation covered areas, and strong seasonal varia tions were found in these areas. Total numbers of fires were 283,683 and 202,543, respectively. In particular, the wildland fires in croplands occurred mainly during summer season and distinguishable increasing trends were found. The correlations be tween number of wildland fires and air pollutants, such as black carbon, organic matter, and carbon monoxide, were also calculated in order to investi gate the intensity of the air pollution caused by the wildland fires. Positive correlation between total col umn carbon monoxide contents and the occurrence of wildland fire was found. In addition, this correla tion was higher than the correlation between fire occurrence and black carbon or organic matter. These results indicate that a significant amount of carbon monoxide originated from the wildland fires and influenced the regional atmospheric environ ment in East Asia.
