本文介绍了1968-1982年在23个国家海洋和大气管理局/气候变化地球物理监测站和国外合作站的离散采样获得的CO/SUB2/数据，并对测量方案和数据质量进行了说明。月、季和年的CO/sub2/浓度由各个站点根据选定的(背景)数据确定。全球CO/sub2/的时间和空间分布产生了CO/sub2/的年和季节纬度梯度、丰度、气载分数、年循环幅度和相位、年循环幅度增长率和全球增长率变化。时间序列数据集揭示了与几个厄尔尼诺/南方涛动事件有关的变化，特别是关于赤道太平洋CO/sub2/源的强度和全球CO/sub2/增长率的变化。CO/Sub2/增长率异常与南方涛动指数高度相关，南方涛动指数与沿赤道吹来的东风信风的强度有关。参考文献54篇，附图17幅，表12篇。
CO/sub 2/ data obtained from discrete sampling during 1968-1982 at 23 National Oceanic and Atmospheric Administration/Geophysical Monitoring for Climatic Change and foreign cooperative stations are presented, together with a description of the measurement program and data quality. Monthly, seasonal, and annual CO/sub 2/ concentrations are determined by the individual stations from select (background) data. Temporal and spatial global CO/sub 2/ distributions yield annual and seasonal latitudinal gradients, abundances, airborne fractions, annual cycle amplitudes and phases, annual cycle amplitude growth rates, and global growth rate variations of CO/sub 2/. The time-series data sets reveal variations related to several El Nino/Southern Oscillation events, particularly with respect to the strength of the CO/sub 2/ source in the equatorial Pacific Ocean and global CO/sub 2/ growth rates. CO/sub 2/ growth rate anomalies correlate highly with the Southern Oscillation Index, which is related to the strength of the easterly trade winds that blow along the equator. 54 references, 17 figures, 12 tables.
