A cross-disciplinary team of researchers will develop a state-of-the-art record of atmospheric CO2 concentrations for the past 400 million years. They will do so by engaging the broader scientific community to revise existing estimates of past CO2 concentrations that were previously made using fossil plant material and minerals that are ‘proxies’ of ancient environmental conditions. The team will also develop a set of numerical models that are capable of simulating the land or ocean environments in which the proxies formed in order to better understand how proxies archive ancient conditions and atmospheric CO2 concentrations. Together these approaches will permit the researchers to build the next-generation record of CO2 concentrations for the last half billion years of Earth history. This record is fundamental to understanding how our planet functions under high and evolving CO2 concentrations. All products of the project (database, software, algorithms) will be broadly disseminated. The project will fund and mentor several students and early career scientists and two planned educational and outreach activities will ensure that the results are accessible to Earth and Environmental Science students and to the public.The community project CO2PIP (CO2 Proxy Integration Project) will advance the science of paleo-CO2 reconstruction and build a statistically robust multi-proxy atmospheric CO2 record for the Phanerozoic. This will be done through the development of forward proxy system models of the conditions and processes that govern the CO2 signal in commonly used CO2 proxies. The broader scientific community will be engaged to modernize primarily terrestrial-based CO2 proxy records and build a standardized and FAIR paleo-CO2 proxy data repository. Four proxy system models will be statistically integrated with the vetted and modernized proxy data using inversion analysis to produce quantitative, data-driven CO2 reconstructions for individual records and to generate a robust, quantitative reconstruction of paleo-CO2. Digital infrastructure for presenting and archiving the CO2 compilation and community endorsed outputs will ensure full accessibility to the scientific community and public. This research will advance our understanding of proxy sensitivities to individual controls that affect the accuracy and precision of CO2 estimates and improve comparability of paleo-CO2 records, thus refining our understanding of the evolution of paleo-CO2 through the past half billion years of Earth history.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

一个跨学科的研究人员将在过去4亿年中建立最先进的大气二氧化碳浓度记录。他们将通过吸引更广泛的科学界来修改以前使用化石植物材料和矿物质的现有二氧化碳浓度的估计，这些材料和矿物质是古代环境条件的“代理”。该团队还将开发一组数字模型，这些模型能够模拟代理形成的土地或海洋环境，以便更好地了解代理如何存档古代条件和大气二氧化碳浓度。这些方法共同使研究人员能够在地球历史的过去十亿年中建立下一代二氧化碳浓度的记录。该记录是了解我们的星球在高和不断发展的二氧化碳浓度下的功能至关重要。该项目的所有产品（数据库，软件，算法）将被广泛传播。 The project will fund and mentor several students and early career scientists and two planned educational and outreach activities will ensure that the results are accessible to Earth and Environmental Science students and to the public.The community project CO2PIP (CO2 Proxy Integration Project) will advance the science of paleo-CO2 reconstruction and build a statistically robust multi-proxy atmospheric CO2 record for the Phanerozoic.这将通过开发在常用CO2代理中控制CO2信号的条件和过程的正向代理系统模型来完成。更广泛的科学界将参与现代化主要基于陆地的CO2代理记录，并建立标准化且公平的古CO2代理数据存储库。使用反转分析，将在统计上与四个代理系统模型与经过审查和现代化的代理数据集成，以产生定量的，数据驱动的二氧化碳重建，以实现单个记录，并生成对古CO2的强大定量重建。用于展示和存档CO2汇编和社区认可的产出的数字基础架构将确保对科学界和公众的全面访问。这项研究将提高我们对对个体控制的敏感性的理解，这些控制能影响二氧化碳估计的准确性和精度，并提高古CO2记录的兼容性，该奖项反映了NSF的法定任务，并被认为是通过基金会的智力优点和更广泛影响的审查标准来通过评估来获得的支持。
