2018年中国多尺度高分辨率污染物排放清单

中国全国排放清单，包括全国SO2, NOx, NMVOC, NH3, PM2.5, PM10, Hg, Cl等多种污染物的人为源排放清单，清单已更新至2018年。提供网格化的全年各污染物排放txt格式数据及时间分配系数。使用者可根据自身需要的网格进行插值处理，从而获取中国不同网格数/分辨率的人为源排放清单。网格分辨率为27 km × 27 km，网格范围包含中国大陆及周边部分地区。排放单位分别为：VOC机制物种排放的单位是mol/年；常规污染物排放的单位是吨/年。物种机制分别为：VOC机制：cb6；气溶胶机制：ae6。网格信息：原点坐标（-3132000.000， -2457000.000），中心点（34°N，110°E），真纬度（25°N，40°N），网格数232×182。China National Emission Inventory is a comprehensive anthropogenic emission inventory covering various pollutants including SO2, NOx, NMVOC, NH3, PM2.5, PM10, Hg, Cl and others, which has been updated to 2018. Gridded annual emission data in TXT format for each pollutant and temporal allocation factors are provided. Users may perform interpolation processing according to their desired grid specifications to obtain anthropogenic emission inventories with different grid counts or resolutions across China. The grid resolution is set at 27 km × 27 km, and the grid scope encompasses mainland China and some surrounding regions. The emission units are specified as follows: the unit for VOC mechanism species is mol/year, while the unit for conventional pollutants is ton/year. The adopted chemical mechanisms are cb6 for the VOC mechanism and ae6 for the aerosol mechanism. Detailed grid information is as follows: origin coordinates (-3132000.000, -2457000.000), center point (34°N, 110°E), true latitudes (25°N, 40°N), and a total grid count of 232×182.
