我们提出并讨论了一个新的网格排放数据集，涵盖历史时期(1850-2000年)，以十年为增量，在经纬度为0.5度的水平分辨率下。这份清单的主要目的是提供一致的反应性气体和气溶胶的网格排放，用于气候模型对比计划5(CMIP5)支持政府间气候变化专门委员会(IPCC)第五次评估报告(AR5)的气候模型所需的化学模型模拟。我们对2000年清单的最佳估计是将现有的区域和全球清单结合起来，以获取目前可获得的最佳信息；使用40个区域和12个部门来综合各种来源。然后，每个区域和部门的每个排放化合物的历史重建被迫与我们2000年的估计一致，以确保过去和2000年排放量之间的连续性。来自两个化学-气候模式的模拟被用来测试这里描述的排放数据集捕捉大气臭氧、一氧化碳和气溶胶分布的长期变化的能力。模拟的北部中纬度地面和对流层中层臭氧的长期变化没有观测到的那么快。然而，在这个纬度范围以外的站点，无论是在当前趋势还是在长期趋势上，都显示出更好的一致性。模式模拟表明，MACE中心站的一氧化碳浓度被低估了；然而，在有限的观测期内，似乎相当好地捕捉到了长期趋势。模拟的格陵兰岛硫酸盐和黑碳沉积与整个模拟期间的冰芯观测结果非常吻合。最后，气溶胶光学厚度和其他气溶胶诊断结果与以前发表的估计和观测结果吻合得很好。
We present and discuss a new dataset of gridded emissions covering the historical period (1850-2000) in decadal increments at a horizontal resolution of 0.5 degrees in latitude and longitude. The primary purpose of this inventory is to provide consistent gridded emissions of reactive gases and aerosols for use in chemistry model simulations needed by climate models for the Climate Model Intercomparison Program #5 (CMIP5) in support of the Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment report (AR5). Our best estimate for the year 2000 inventory represents a combination of existing regional and global inventories to capture the best information available at this point; 40 regions and 12 sectors are used to combine the various sources. The historical reconstruction of each emitted compound, for each region and sector, is then forced to agree with our 2000 estimate, ensuring continuity between past and 2000 emissions. Simulations from two chemistry-climate models are used to test the ability of the emission dataset described here to capture long-term changes in atmospheric ozone, carbon monoxide and aerosol distributions. The simulated long-term change in the Northern mid-latitudes surface and mid-troposphere ozone is not quite as rapid as observed. However, stations outside this latitude band show much better agreement in both present-day and long-term trend. The model simulations indicate that the concentration of carbon monoxide is underestimated at the Mace Head station; however, the long-term trend over the limited observational period seems to be reasonably well captured. The simulated sulfate and black carbon deposition over Greenland is in very good agreement with the ice-core observations spanning the simulation period. Finally, aerosol optical depth and additional aerosol diagnostics are shown to be in good agreement with previously published estimates and observations.
