本文介绍了1976 - 1984年期间在澳大利亚和南极地区地面观测大气中二氧化碳浓度的结果。这些观测补充了已经报告的那些观测，这些观测是根据从同一区域的整个对流层和低平流层的飞机上收集的样本进行的。提供了格里姆角（40°41'S; 144° 41 'E）4个地点的数据。莫森（67°37'S; 62° 52 'E）、麦觉理岛（54°29'S; 158° 58' E）和Wilbinga（31°25'S; 115° 33 'E）以及在穿越南大洋的船上收集的空气样本。到目前为止，所描述的最全面的监测方案是格里姆角天文台的监测方案，自1976年以来一直在进行连续的原位观测。方法被认为是选择数据来代表基线或背景浓度和描述的自然变化的CO2浓度，包括小时内和日变化，季节性周期，年际和长期趋势。在数据所代表的时期内，浓度的平均增长率为1.5 ppmv yr-1。从这些方案中选择的数据和类似的数据集收集在阿姆斯特丹岛和新西兰的其他国际项目之间的比较。DOI：10.1111/j.1600-0889.1987.tb00269.x
Observations of the atmospheric carbon dioxide (CO 2 ) concentration made at surface locations in the Australian and Antarctic regions are presented for the period 19761984. These observations complement those already reported which were based on samples collected from aircraft throughout the troposphere and lower stratosphere in the same region. Data are presented for 4 sites, Cape Grim (40°41'S; 144°41'E). Mawson (67°37'S; 62°52'E), Macquarie Island (54°29'S; 158°58'E) and Wilbinga (31°25'S; 115°33'E) and for air samples collected on board ships traversing the Southern Ocean. By far the most comprehensive monitoring program described is that for the Cape Grim Observatory, where continuous in situ observations have been made since 1976. Methods are considered for the selection of data to represent the baseline or background concentration and a description is given of the natural variability of CO 2 concentration, including within-hour and diurnal variability, seasonal cycles, interannual and secular trends. The average rate of concentration increase over the period represented by the data was 1.5 ppmv yr -1 . A comparison is made between the selected data from these programs and similar data sets collected at Amsterdam Island and in New Zealand by other international projects.
