夏威夷莫纳罗亚天文台及其附近的大气二氧化碳浓度是一项长期计划的前六年(1958-1963年)的报告，该计划旨在记录煤炭和石油燃烧对大气和世界海洋中二氧化碳气体分布的影响。这里报告的大部分测量是在莫纳罗亚天文台用连续记录的红外气体分析仪获得的。还报道了在莫纳罗亚岛、夏威夷迎风海岸和夏威夷群岛附近的飞机上收集的261个玻璃烧瓶中的离散空气样本的测量结果。结果表明：(1)莫纳罗亚观测站CO2浓度随季节变化，平均幅度为6ppm，并以年均0.7ppm的速度递增；(2)这些变化反映了夏威夷附近信风层上空大气的区域性变化。(3)除夏季略低的月份外，信风层的CO2浓度与高空基本相同。(4)莫纳罗亚峰顶附近火山释放的二氧化碳和森林覆盖下的山坡对二氧化碳的吸收影响着莫纳罗亚观测站的二氧化碳浓度，但不会严重干扰区域变化的测定。
The concentration of atmospheric carbon dioxide at and near Mauna Loa Observatory, Hawaii, is reported for the first six years (1958–1963) of a long-term program to document the effects of the combustion of coal and petroleum on the distribution of CO2 gas in the atmosphere and in the world's oceans. The majority of the measurements reported here were obtained at Mauna Loa Observatory with a continuously recording infrared gas analyzer. Also reported are measurements of 261 discrete samples of air collected in glass flasks on Mauna Loa, on the windward coast of Hawaii, and from aircraft near the Hawaiian Islands. The following results have been obtained: (1) The CO2 concentration at Mauna Loa Observatory varies with season with an average amplitude of 6 ppm and is increasing at the average rate of 0.7 ppm per year. (2) These variations reflect regional changes in the air which lies above the trade wind layer near Hawaii. (3) The concentration of CO2 in the trade wind layer is essentially the same as aloft except during the summer months when it is slightly lower. (4) Volcanic emanations of CO2 near the summit of Mauna Loa and uptake of CO2 on the forested lower slopes of the mountain influence the concentration of CO2 at Mauna Loa Observatory but do not seriously interfere with the determination of regional changes.
