多种生物质开放燃烧排放清单的建立及模拟评估文章被ACP接收(Our work on quantification and evaluation of emissions from open biomass burning with multiple methods accepted by Atmos Chem Phys)

       我们分别基于自下而上、卫星火点辐射能量和观测约束三种方法估算了2005-2015年长三角地区生物质开放燃烧大气污染物排放。通过化学传输模拟评估,基于观测约束获得排放的模拟结果与观测的差异最小。在2010、2012和2014年典型的生物质开放燃烧事件期间,生物质开放燃烧排放对颗粒物污染有着重要的贡献。该工作揭示了中国重要大气污染源排放的不确定性,并阐明了未来进行排放估算改进的可能途径。
       祝贺杨杨!

 

   We quantified the emissions of open biomass burning (OBB) using the bottom-up, FRP-based and constraining method, respectively, for 2005-2015 in the Yangtze River Delta region.Among the three inventories, the smallest discrepancies between simulated and observed particle concentrations were found during the OBB season when the constrained OBB inventory was applied in the chemistry transport modeling. Contributions of OBB to particulate pollution was estimated to be significantly enhanced for typical OBB events in 2010, 2012 and 2014. The work revealed the uncertainty of air pollutant emissions from an important source in China and  demonstrated the possible ways to improve the emission estimation in the future.
    Congratulations to Yang Yang!
