Antarctic Snow Accumulation Reconstruction from 1801-2000 CE

Advik Eswaran from Princeton University generated an annually resolved, gridded reconstruction of snow accumulation anomalies over Antarctica for the period 1801-2000 CE. The reconstruction uses the Last Millennium Reanalysis data assimilation framework, a multi-model ensemble of nine CMIP5 climate simulations, and a database of water isotope and accumulation ice core records from the Pages 2k consortium and other individual sites.

Use Cases

• Analyzing long-term trends in Antarctic snow accumulation based on the 200-year reconstructed time series.
• Validating climate model simulations of the Antarctic region using the reconstructed gridded anomaly data.
• Studying the relationship between water isotopes and snow accumulation in paleoclimate records.
• Investigating spatial patterns of accumulation variability across Antarctica from the gridded reconstruction.

Strengths

• Covers a 200-year time period from 1801 to 2000 CE.
• Integrates data from a multi-model ensemble of nine named CMIP5 climate simulations.
• Incorporates a specified database of ice core records from the Pages 2k consortium and several individual core sites.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
