An annually resolved reconstruction of gridded snow accumulation anomalies over Antarctica, from 1801-2000 CE. Reconstructions are generated using the Last Millennium Reanalysis data assimilation framework (Hakim et al., 2016; Tardif et al., 2019), a comprehensive ice core proxy database, and a multi-model ensemble of climate simulations. We incorporate a database of water isotope (Stenni et al., 2017) and accumulation (Thomas et al., 2017) ice core records from the Pages 2k consortium, in addition to individual records from the South Pole ice core (Kahle et al., 2021), Derwael Ice Rise (Philippe et al., 2016), and the PIG2010, DIV2010, and THW2010 sites (Criscitiello et al., 2013). The multi-model ensemble is constructed using nine CMIP5 Last Millennium Simulations: CCSM4 (Gent et al., 2011), iCESM (Brady et al., 2019), BCC-CSM1.1 (Wu et al., 2014), CSIRO Mk3L (Phipps et al., 2012), FGOALS-s2 (Bao et al., 2013), GISS-E2-R (Schmidt et al., 2014), HadCM3 (Collins et al., 2001), IPSL-CM5A-LR (Dufresne et al., ...
