在国际全球大气化学方案的全球排放清单活动（GEIA）的框架下，编制了1985年前后硫氧化物和氮氧化物的两套全球人为排放清单。这两套清单具有不同的时间、部门和垂直分辨率。两者都是使用相同的数据集编制的；通过使用更详细的区域数据集，对全球排放的默认数据集进行了改进。本文报告了年度单垂直级库存的编制，称为1A版；清单文件通过匿名文件转换协议（FTP）提供给科学界。现有的全球库存和区域库存已更新并合并在1度x 1度的经纬度网格上。由此产生的全球人为排放为65 Tg S年（-1）和21 Tg N年（-1）；定性的不确定性估计是在区域基础上进行的。硫氧化物和氮氧化物的排放主要集中在北美东部和整个欧洲的人口稠密和工业化地区；其他较小的大排放区域与工业发达的人口稠密地区有关，或与开采燃料或矿物储备有关。氮硫排放物的摩尔比反映了污染源的总体特征；在工业化和人口稠密地区，其值一般在0.33至10之间，但在其他地区则相差很大。我们建议那些需要硫或氮排放清单的人在GEIA清单上进行标准化，我们认为GEIA清单是权威的，并且通过匿名FTP免费提供给所有用户。
Two sets of global inventories of anthropogenic emissions of both oxides of sulfur and oxides of nitrogen for circa 1985 have been produced under the umbrella of the Global Emissions Inventory Activity (GEIA) of the International Global Atmospheric Chemistry Program. The two sets of inventories have different temporal, sectoral, and vertical resolution. Both were compiled using the same data sets; default data sets of global emissions have been refined via the use of more detailed regional data sets. This article reports on the compilation of the annual, one-vertical-level inventories, called version 1A; the inventory files are available to the scientific community via anonymous file transform protocol (FTP). Existing global inventories and regional inventories have been updated and combined on a 1 degrees x 1 degrees longitude/latitude grid. The resulting global anthropogenic emissions are 65 Tg S yr(-1) and 21 Tg N yr(-1); qualitative uncertainty estimates have been assigned on a regional basis. Emissions of both SOx and NOx are strongly localized in the highly populated and industrialized areas of eastern North America and across Europe; other smaller regions of large emissions are associated with densely populated areas with developed industries or in connection with exploitation of fuels or mineral reserves. The molar ratio of nitrogen to sulfur emissions reflects the overall character of sources; its value is generally between 0.33 and 10 for industrialized and heavily populated areas but varies over a wide range for other areas. We suggest that those requiring sulfur or nitrogen emission inventories standardize on the GEIA inventories, which we believe are authoritative and which are freely available to all users by anonymous FTP.
