Paleo-CO2 Data Archive

These data were compiled from published paleo-CO₂ data that have been assembled 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 samples, and the compilation includes data derived from multiple proxies including Phytoplankton, Boron, Stomatal Frequencies, Leaf Gas Exchange, Liverworts, Land Plant Carbon Isotopes, Paleosols, and Nahcolite.  These are used in the interactive archive 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.ncdc.noaa.gov/paleo/study/35079).
