摘要：

Open biomass burning (BB) frequently occurs in spring over Southeast Asia (SEA). The concentration of fine particulate (PM 2.5 ) produced by BB and its impacts on air quality in downwind aeras exhibit significant interannual variations, which are controlled by emission intensity and meteorological circulation. In this study, a regional air quality model system (RAQMS) was applied to investigate the contributions of BB emissions in SEA to atmospheric PM 2.5 concentrations over South China in March (a spring month) during 2009 -2018 and their interannual variations. Higher near -surface BB-PM 2.5 (refers to the PM 2.5 produced by BB in SEA) concentrations and contributions were mainly distributed in the source region and its vicinity, while the higher tropospheric BBPM 2.5 concentrations and contributions were characterized by a long belt extending from BB source regions to Yangtze River Delta (YRD) in South China. Combined with the vertical distribution of BB-PM 2.5 on the transported path profile, it indicated that higher BB-PM 2.5 concentrations were mainly concentrated in 0-1500 m above the ground over source regions, while the maximum BB-PM 2.5 concentrations in the downwind area were distributed in 1500-3500 m above the ground. The monthly mean tropospheric BB-PM 2.5 concentrations were higher in March 2009, 2010, 2012, and 2013, with evident correlation with interannual variation of BB emissions. Sensitivity experiments suggested that the near -surface and tropospheric BB-PM 2.5 concentrations over South China had changed by -48.1%-190.5% and -48.0%-213.8%, respectively in March 2009 -2018 by fixing BB emissions unchanged at the mean of the 10 years, being greater than the changes caused by meteorological conditions and other affecting factors (-20%). In addition, the relative contributions of BB emission from various regions in SEA on the mean near -surface and tropospheric BB-PM 2.5 concentrations over South China were further identified.
