LarsAckermann GMD Iceberg 2023: Earth System Model Output with Interactive Icebergs

Model output from the AWI-ESM2.1 Earth system experiment with interactive icebergs, published by Lars Ackermann of the Alfred-Wegener-Institut Helmholtz-Zentrum für Polar- und Meeresforschung. It contains multi-century timeseries, including 700-year records of global ocean temperature and Antarctic Bottom Water, plus yearly 3D ocean data. Mean outputs are averaged over the final 100 model years.

Use Cases

• Analyze long-term ocean temperature trends based on 700-year global temperature timeseries.
• Model Antarctic Bottom Water (AABW) formation and its Indo-Pacific sector variability based on provided timeseries.
• Study iceberg freshwater and heat fluxes on ocean circulation based on yearly 2D flux data.
• Investigate ocean stratification using yearly 3D Väisälä frequency data.
• Examine iceberg trajectories and dimensions based on buoy files containing location and velocity information.

Strengths

• Includes 700-year timeseries for long-term climate trend analysis.
• Provides 3D spatial data for ocean temperature, salinity, and vertical velocities.
• Contains model output from a peer-reviewed experiment published in a scientific journal.

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.
