This project will support an effort to recover and make available to posterity a larger number of data assets that are part of the iconic Keeling carbon dioxide (CO2) record. The first measurements of atmospheric CO2 to be made with methods of sufficient quality to document changes were those of the late Charles D. Keeling, who initiated a program in the late 1950s at the Scripps Institution of Oceanography. This program has continued under the current principal investigator to the present, sustaining the world's longest time series of the ocean and atmosphere, including the well-known Mauna Loa record as well as records from a flask sampling program from an array of stations distributed from the Arctic to the Antarctic.A major component of the study of global climate change is to document changes in the cycling of carbon in the Earth system. This task requires not just ongoing measurements but also careful comparison to records made in the past. Results from this program have been made available through scientific publications, submissions to databases (e.g., CDIAC, the Carbon Dioxide Information Analysis Center) as well as more recently through a dedicated webpage, http://scrippsco2.ucsd.edu. The publicly available data, however, comprise only a fraction of the total body of measurements made by the program. For example, flask CO2 data from extensive ship, airborne, and land-based surveys from the 1950s to 1980s are unavailable in a form amenable to analysis. In addition, these early data can now be interpreted in the context of reanalysis of observed atmospheric wind fields extending back to the 1950s. Many other valuable resources generated at Scripps are also not available in convenient or "final" form. Multi-decadal records from Barrow, Alaska and at La Jolla itself, comprise overlapping measurements from two or more programs or instruments that have not been suitably merged and reconciled. This project will focus on recovering and posting these data in modern digital formats.Potentially valuable meteorological data remains on hand-recorded log sheets, strip charts, magnetic tapes, computer punch cards, or old computer printouts. The key to unlocking these resources is in the minds of senior personnel who are within a few years of the end of their careers. Corrections to the Scripps manometric scale that result from recently-resolved slow deformation of glass volumes with time remain to be finalized. This project will support a concerted effort to develop readily available datasets from these resources, including recovering raw data, reprocessing as needed, merging with other datasets, addressing issues of calibration, presenting data on the group webpage, and archiving at CDIAC.These activities could enable diverse investigations into the distant future. The work is of very broad importance to society in the context of global climate change. The work will further sustain elements of the Scripps CO2 program which is widely considered as the "true beginning" for stories covering the topic of rising CO2 and global warming.

该项目将支持恢复并向后代提供大量数据资产的努力，这些数据资产是标志性的基林二氧化碳（CO2）记录的一部分。 第一次测量大气中二氧化碳的方法质量足以记录变化是已故的查尔斯D。基林在20世纪50年代末在斯克里普斯海洋研究所发起了一个项目。 这个项目在现任首席研究员的领导下一直持续到现在，维持着世界上最长的海洋和大气的时间序列，包括著名的莫纳罗亚山记录，以及从北极到舌齿山分布的一系列站的烧瓶采样计划记录。全球气候变化研究的一个主要组成部分是记录地球系统中碳循环的变化。 这项任务不仅需要持续的测量，还需要与过去的记录进行仔细的比较。该项目的结果已通过科学出版物、数据库提交文件（例如，CDIAC，二氧化碳信息分析中心），以及最近通过一个专门的网页，http://scrippsco2.ucsd.edu。 然而，公开的数据只占该计划所做测量的一小部分。 例如，从20世纪50年代到80年代的广泛船舶，航空和陆基调查中获得的烧瓶CO2数据无法以适合分析的形式获得。 此外，这些早期数据现在可以在重新分析可追溯到20世纪50年代的观测大气风场的背景下进行解释。 Scripps产生的许多其他有价值的资源也无法以方便或“最终”的形式提供。来自阿拉斯加巴罗和拉霍亚本身的多年代际记录包括来自两个或多个程序或仪器的重叠测量，这些程序或仪器尚未适当合并和协调。 这个项目将着重于恢复和以现代数字格式发布这些数据，可能有价值的气象数据仍然保存在手工记录的日志表、条形图、磁带、计算机穿孔卡或旧计算机打印机上。 释放这些资源的关键是在高级人员的头脑中，他们的职业生涯在几年内结束。 最近解决的玻璃体积随时间的缓慢变形导致的斯克里普斯测压标度的校正仍有待最终确定。 该项目将支持通过协调一致的努力，从这些资源中开发现成的数据集，包括恢复原始数据，根据需要进行再处理，与其他数据集合并，解决校准问题，在小组网页上展示数据，并在CDIAC存档。 在全球气候变化的背景下，这项工作对社会具有非常广泛的重要性。 这项工作将进一步维持斯克里普斯二氧化碳计划的元素，该计划被广泛认为是涵盖二氧化碳上升和全球变暖主题的故事的“真正开始”。
