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.

龙骨曲线是一个图，显示了自1958年以来已故的C. D. Keeling和他的同事来自Scripps Oceanography Institution of Scripps Oceanography（SIO）以来，全球游离对流层中二氧化碳的混合比增加。 该图记录了行星碳代谢的许多科学基本特性，包括归因于人为化石燃料燃烧的大气二氧化碳中的世俗增长，植被吸收CO2的年度季节性变化，以及通过推断海洋和陆层水分的差异化石燃料碳燃料碳的差异。 到现在为止，Keeling曲线是讨论全球气候变化问题和全球变暖的标志性。该奖项是为SIO测量和烧瓶采样网络以及C. D. Keeling开创的精确高精度测量的额外资金。 许多与C. D. Keeling时间序列验证相关的未完成任务，包括确认历史测量测量标准以及SIO档案数据集的持续传播。
