Data Product for "Toward a Cenozoic history of atmospheric CO2"

These data were vetted and revised from published paleo-CO2 data (original estimates archived at https://zenodo.org/uploads/8052599) by an international group of proxy experts supported through an NSF-funded Research Coordination Network. It brings together paleo-CO2 reconstruction data from terrestrial and marine archives, and the compilation includes estimates derived from multiple proxies including Phytoplankton, Boron, Stomatal Frequencies, Leaf Gas Exchange, Liverworts, Land Plant d13C, Paleosols, and Nahcolite. Data are visualized in an interactive product plot made available on the Paleo-CO2 project web page at (https://www.paleo-co2.org) and are also archived in the NCDC database (https://www.ncei.noaa.gov/pub/data/paleo/climate_forcing/trace_gases/Paleo-pCO2/product_files/).本数据集由美国国家科学基金会（NSF）资助的研究协调网络支持的国际代用指标专家团队，对已发表的古二氧化碳（paleo-CO2）数据进行审核与修订而成（原始估算数据存档于https://zenodo.org/uploads/8052599）。本次汇编整合了来自陆地与海洋档案的古CO2重建数据，涵盖基于多种代用指标的估算结果，包括浮游植物（Phytoplankton）、硼（Boron）、气孔频率（Stomatal Frequencies）、叶片气体交换（Leaf Gas Exchange）、地钱（Liverworts）、陆生植物碳同位素比值d13C（Land Plant d13C）、古土壤（Paleosols）以及天然碱（Nahcolite）。数据集的可视化成果以交互式产品绘图形式发布于古CO2项目官方网站（https://www.paleo-co2.org），同时也存档于美国国家气候数据中心（NCDC）数据库（https://www.ncei.noaa.gov/pub/data/paleo/climate_forcing/trace_gases/Paleo-pCO2/product_files/）。
