A Study of the Global Carbon Cycle Based on Measurements of the Abundance and Isotopic Composition of Atmospheric Carbon Dioxide (CO2)

基于大气二氧化碳(CO2)丰度和同位素组成测量的全球碳循环研究

基本信息

项目摘要

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.
基林曲线是一个曲线图,显示了自1958年以来在莫纳罗亚天文台连续测量的全球自由对流层中二氧化碳混合比的增加。D.基林和他的同事来自斯克里普斯海洋研究所(SIO)。 该图记录了行星碳代谢的一些科学基本特性,包括归因于人类化石燃料燃烧的大气CO2的长期上升,植被吸收CO2的年度季节性变化,以及推断海洋和陆地汇对化石燃料碳的差异吸收。 到目前为止,基林曲线是全球气候变化问题和全球变暖讨论的标志。该奖项是对SIO测量和烧瓶采样网络以及C. D.基林 与C. D. Keeling时间序列,包括历史测压测量的确认,以及SIO档案数据集的持续传播也将完成。
