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 the Alfred-Wegener-Institut. It contains multi-century timeseries and spatial averages of ocean temperature, salinity, and sea-ice height. The data is associated with a 2023 publication in the EGUsphere journal.

Use Cases

• Analyzing long-term trends in global ocean temperature based on the 700-year timeseries.
• Studying Antarctic Bottom Water (AABW) formation and variability in the Indo-Pacific sector.
• Investigating the three-dimensional structure of ocean properties like temperature and salinity from the yearly 3D data.
• Modeling the impact of interactive icebergs on sea-ice height and ocean stratification using the provided variables.

Strengths

• Includes a 700-year timeseries for key climate variables like global ocean temperature.
• Provides spatially resolved data, including zonal means for major ocean basins (Atlantic, Pacific, Indian).
• Contains multi-variable output, such as 3D ocean temperature, salinity, vertical velocity, and Väisälä frequency.

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.
