Antarctic Temperature and Isotope Data from Past Millennium Climate Model Simulation

800-1999 CE time series of Antarctic two-metre air temperature, surface temperature, total precipitation, and stable isotopes in precipitation from the ECHAM5/MPI-OM-wiso past1000 climate model simulation. The data, produced by Thomas Münch of the Alfred-Wegener-Institut Helmholtz-Zentrum für Polar- und Meeresforschung, covers 768 model grid cells south of 60° S, with 442 cells over the Antarctic continent containing non-NA values. Time series are provided at monthly and annual resolution, including precipitation-weighted averages.

Use Cases

• Analyzing long-term Antarctic temperature trends based on monthly and annual time series.
• Studying the relationship between precipitation and stable isotope composition based on oxygen-18 and deuterium data.
• Validating isotope-enabled climate models against paleoclimate proxies based on the past millennium simulation.
• Investigating spatial climate patterns over Antarctica based on the provided time-invariant mean fields.

Strengths

• Covers a 1200-year period from 800 to 1999 CE.
• Provides data for 442 model grid cells over the Antarctic continent.
• Includes both monthly resolution data and derived annual resolution data with precipitation-weighted averages.
• Comes with processing code (bash and R scripts) for reproducibility.

Limitations

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