This new version of CO2 composite replaces the old version of Luthi et al. (2008), which contains the analytical bias described in Bereiter et al. 2015 and lower quality data in other sections. For details about the improvements relative to the previous version see supplementary information of Bereiter et al. 2015. For detailed references of all records refer to the supplemetary information of Bereiter et al. 2015. For latest anthropogenic data refer to NOAA/Mauna Loa record. Age unit is in years before present (yr BP) where present refers to 1950 AD. Note, not all individual records provided are part of the composite. If millennial scale or smaller details of the composite are studied, we recommend to look into all records available for that period and not only in the composite. Composite built from the following: -51-1800 yr BP: Law Dome (Rubino et al. 2013) 1.8-2 kyr BP: Law Dome (MacFarling Meure et al. 2006; https://doi.org/10.25921/g6kd-k189) 2-11 kyr BP: Dome C (Monnin et al. 2001 + 2004; https://doi.org/10.25921/ggj5-vt17, https://doi.org/10.25921/aktb-0t39) 11-22 kyr BP: WAIS (Marcott et al. 2014) minus 4 ppmv (see text) 22-40 kyr BP: Siple Dome (Ahn et al. 2014) 40-60 kyr BP: TALDICE (Bereiter et al. 2012; https://doi.org/10.25921/4vks-ex31) 60-115 kyr BP: EDML (Bereiter et al. 2012; https://doi.org/10.25921/4vks-ex31) 105-155 kyr BP: Dome C Sublimation (Schneider et al. 2013) 155-393 kyr BP: Vostok (Petit et al. 1999; https://doi.org/10.25921/kcry-ae86) 393-611 kyr BP: Dome C (Siegenthaler et al. 2005) 612-800 kyr BP: Dome C (Bereiter et al. 2014) ABSTRACT SUPPLIED BY ORIGINATOR: The European Project for Ice Coring in Antarctica Dome ice core from Dome C (EDC) has allowed for the reconstruction of atmospheric CO2 concentrations for the last 800,000 years. Here we revisit the oldest part of the EDC CO2 record using different air extraction methods and sections of the core. For our established cracker system, we found an analytical artifact, which increases over the deepest 200 m and reaches 10.1 +/- 2.4 ppm in the oldest/deepest part. The governing mechanism is not yet fully understood, but it is related to insufficient gas extraction in combination with ice relaxation during storage and ice structure. The corrected record presented here resolves partly - but not completely - the issue with a different correlation between CO2 and Antarctic temperatures found in this oldest part of the records. In addition, we provide here an update of 800,000 years atmospheric CO2 history including recent studies covering the last glacial cycle.
