20th century winds, pressure, and temperature around Antarctica from single-proxy data assimilation
<p>Please cite <a href="https://doi.org/10.5194/tc-2023-16">O'Connor et al., 2023</a> (preprint available in The Cryosphere Discussions) when using these single-proxy reconstruction datasets. The reconstructions generated using all proxy data (O'Connor et al., 2021) are archived <a href="https://zenodo.org/record/5507607">here</a>.</p> <p>This dataset contains four sets of single-proxy reconstructions of annually resolved zonal surface wind (us), sea level pressure (psl), and surface temperature (tas) anomalies around Antarctica over the period 1900 to 2005 CE. The reconstructions were generated using the Last Millennium Reanalysis data assimilation framework (<a href="https://agupubs.onlinelibrary.wiley.com/doi/full/10.1002/2016JD024751">Hakim et al., 2016</a>), adapted for Antarctic atmospheric reconstructions following the methods from <a href="https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2021GL095999">O'Connor et al., 2021</a>. The reconstructions were generated using the same proxy databases and methods as outlined in O'Connor et al., 2021, but we only assimilate proxies from ice cores or coral records in each reconstruction.</p> <p>This dataset contains four sets of reconstructions, based on two different climate model simulation priors and either ice cores or coral assimilated:</p> <ol> <li>CESM LM prior, ice cores only</li> <li>CESM LM prior, corals only</li> <li>PACE prior, ice cores only</li> <li>PACE prior, corals only</li> </ol> <p>The CESM LM prior is drawn from the iCESM Last Millennium Ensemble (<a href="https://doi.org/10.1029/2019PA003625">Stevenson et al., 2019</a>) and includes only natural forcings. The PACE prior is drawn from the CESM1 Pacific Pacemaker Ensemble (“PACE”; <a href="https://doi.org/10.1175/JCLI-D-16-0844.1">Deser et al., 2017</a>) and includes historical anthropogenic forcings. For each reconstruction, there are three netCDF files containing the ensemble mean (mean of 100 ensemble members) for each climate field. The anomaly reference period is 1961-1990.</p>

Apatite fission track data from debris from the basal ice of the Byrd ice core, central West Antarctica
<p>This dataset comprises of 10 apatite fission track ages. Apatite grains were picked out of the 75-150 micron size fraction of debris melted from two intervals of basal ice from the Byrd ice core. The Byrd ice core was drilled at 80<i><strong>°</strong></i> 0.1'S, 119<i><strong>°</strong></i> 31.0'W at Byrd Station, West Antarctica, in January 1968.</p>
Zircon U-Pb ages of debris from the basal ice of the Byrd ice core, central West Antarctica
<p>This dataset comprises of 16 zircon U-Pb ages. Zircon grains were picked out of the 75-150 micron size fraction of debris melted from two intervals of basal ice from the Byrd ice core. The Byrd ice core was drilled at 80<i><strong>°</strong></i> 0.1'S, 119<i><strong>°</strong></i> 31.0'W at Byrd Station, West Antarctica, in January 1968.</p>
Clay mineralogy of debris from the basal ice of the Byrd ice core, central West Antarctica
<p>This dataset contains the clay mineral assemblage of debris melted from three intervals of basal ice from the Byrd ice core. Analyses were conducted on the <2 micron fraction. The ice core the debris was extracted from was drilled at 80<i><strong>°</strong></i> 0.1'S, 119<i><strong>°</strong></i> 31.0'W at Byrd Station, West Antarctica, in January 1968.</p>
