本文介绍了全球大气CO分布的综合研究。主要结果如下：（1）在北方对流层上层，CO混合比在0.10 ~ 0.15ppm之间变化，只有少数例外。(2)在北大西洋上空的行星边界层和西欧上空的高指数情况下，如果避免当地来源，CO浓度范围为0.16至0.30 ppm。(3)从副热带对流层中层的数据显示，没有显着的差异，两个半球之间，这意味着（至少对南半球）的存在下，重要的天然CO源。(4)大西洋10°S至60°N、30°W的表层沃茨中的CO浓度比大气平衡值高10至40倍。大部分海洋似乎是大气CO的重要来源。（5）北方对流层顶CO的观测结果表明，对流层顶以上的CO含量迅速减少。平流层是对流层CO的主要汇。
A comprehensive study of the global distribution of atmospheric CO is described. The essential results can be listed as follows: (1) In the upper troposphere of the northern hemisphere the CO mixing ratio varies between 0.10 and 0.15 ppm, with few exceptions. (2) In the planetary boundary layer over the North Atlantic and at high index situations over western Europe, the CO concentrations range from 0.16 to 0.30 ppm if local sources are avoided. (3) Mid-tropospheric data from the subtropics show no marked difference between the two hemispheres, which implies (at least for the southern hemisphere) the presence of important natural CO sources. (4) Surface waters of the Atlantic ocean from 10°S to 60°N at 30°W have CO concentrations 10 to 40 times higher than the atmospheric equilibrium values. Large portions of the oceans appear to act as an important source for atmospheric CO. (5) Measurements in the tropopause region of the northern hemisphere show rapid decrease of CO above the tropopause. It appears that the stratosphere is the major sink for tropospheric CO.
