CESM2 AIS simulation output (1992-2014): The nonlinear and distinct responses of ocean hea

Historical output from one of four CESM2 simulations exploring Antarctic Ice Sheet freshwater discharge impacts from 1992 to 2014. The data contains global monthly fields for temperature, salinity, dissolved inorganic carbon, meridional overturning circulation, and sea ice fraction at ∼0.9×1.25° horizontal resolution. Tessa Gorte from the University of Colorado Boulder generated this model output.

Use Cases

• Modeling the nonlinear response of ocean heat content to Antarctic freshwater discharge based on the temperature and salinity fields.
• Investigating anthropogenic carbon uptake in the Southern Ocean based on the dissolved inorganic carbon (DIC) fields.
• Analyzing changes in meridional overturning circulation strength and patterns based on the MOC field.
• Studying sea ice extent and concentration variability based on the sea ice fraction field.

Strengths

• Data covers a 23-year historical period (1992-2014) under CMIP6 forcing.
• Global fields have a spatial resolution of ∼0.9×1.25° and a monthly temporal resolution.
• Temperature and salinity variables contain 60 depth levels for detailed vertical analysis.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
