Significant chlorine emissions from biomass burning affect the long-term atmospheric chemistry in AsiaChang, DiLi, QinyiWang, ZheDai, JianingFu, XiaoGuo, JiaZhu, LeiPu, DongchuanCuevas, Carlos A.Fernandez, Rafael P.Wang, WeigangGe, MaofaFung, Jimmy C.

H.Granier, ClaireBrasseur, GuyPozzer, AndreaSaiz-Lopez, A.Song, YuWang, TaoCAM-Chem modelAtmospheric oxidantsBiomass burning emissionChlorine emission inventoryTropospheric halogen chemistry10 pags., 3 figs.Biomass burning (BB) is a major source of trace gases and particles in the atmosphere, influencing air quality, radiative balance, and climate. Previous studies have mainly focused on the BB emissions of carbon and nitrogen species with less attention on chlorine. Reactive chlorine chemistry has significant effects on atmospheric chemistry and air quality. However, quantitative information on chlorine emissions from BB, particularly the long-term trend and associated atmospheric impacts, is limited both on regional and global scales. Here, we report a long-term (2001-2018) high-resolution BB emission inventory for the major chlorine-containing compounds (HCl, chloride, and CH3Cl) in Asia based on satellite observations. We estimate an average of 730 Gg yr-1 chlorine emitted from BB activity in Asia, with China contributing the largest share at 24.2% (177 Gg yr-1), followed by Myanmar at 18.7% and India at 18.3%. Distinct seasonal patterns and significant spatial and interannual variability are observed, mainly driven by human-mediated changes in agricultural activity. By incorporating the newly developed chlorine emission inventory into a global chemistry-climate model (CAM-Chem), we find that the BB-chlorine emissions lead to elevated levels of HCl and CH3Cl (monthly average up to 2062 and 1421 parts per trillion by volume (pptv), respectively), subsequently resulting in noticeable changes in oxidants (up to 3.1% in O3 and 17% in OH radicals). The results demonstrate that BB is not only a significant source of air pollutants but also of oxidants, suggesting a larger role of BB emissions in the atmospheric chemistry and oxidation process than previously appreciated. In light of the projected increase in BB activity toward the end of the century and the extensive control of anthropogenic emissions worldwide, the contribution of BB emissions may become fundamental to air quality composition in the future.This work was supported by the National Natural Science Foundation of China (NSFC) (42122062 and 91744204) and the Research Grants Council of Hong Kong Special Administrative Region (T24/504/17-N, 16209022 and 16201623).
