The Keeling curve is a graph showing the increase in the mixing ratio of carbon dioxide in the global free troposphere as measured continuously since 1958 at the Mauna Loa Observatory by the late C. D. Keeling and his coworkers from Scripps Institution of Oceanography (SIO). This graph registers a number of scientifically fundamental properties of the planetary carbon metabolism including the secular rise in atmospheric CO2 attributed to anthropogenic fossil fuels combustion, the annual seasonal change in the uptake of CO2 by vegetation, and by inference the differential uptake of fossil fuel carbon by the ocean and terrestrial sinks. By now the Keeling curve is iconic for the discussion of global climate change issues and global warming.This award is for an additional three years of funding of the SIO measurement and flask sampling network and the exacting high precision measurements pioneered by C. D. Keeling. A number of uncompleted tasks associated with validation of the C. D. Keeling time series, including confirmation of historic manometric measurementscales and the continued dissemination of SIO archival data sets will also be completed.

基林曲线是由已故斯克里普斯海洋研究所(SIO)的C.D.基林及其同事自1958年以来在莫纳罗亚天文台连续测量的全球自由对流层二氧化碳混合比增加的曲线图。这张图记录了地球碳新陈代谢的一些基本科学性质，包括人为化石燃料燃烧导致大气二氧化碳的长期上升，植被吸收二氧化碳的年度季节变化，以及由此推断海洋和陆地对化石燃料碳的不同吸收。到目前为止，基林曲线是讨论全球气候变化问题和全球变暖的标志性曲线。该奖项是为了表彰对SiO测量和烧瓶采样网络以及C.D.基林开创的精确高精度测量的额外三年资助。还将完成与确认C.D.基林时间序列有关的一些未完成的任务，包括确认历史上的压力计测量结果，以及继续传播SIO档案数据集。
