CESM2 GrIS Simulation: Ocean Heat and Carbon Content (1992-2014)

Historical model output from a CESM2 simulation exploring Greenland Ice Sheet freshwater discharge impacts on the Southern Ocean. The data contains monthly global fields for temperature, salinity, dissolved inorganic carbon, meridional overturning circulation, and sea ice fraction from January 1992 to December 2014. Tessa Gorte from the University of Colorado Boulder produced this output using CMIP6 historical forcing.

Use Cases

• Analyze anthropogenic ocean heat content changes based on the temperature field.
• Investigate anthropogenic carbon content dynamics based on the dissolved inorganic carbon fields.
• Study changes in meridional overturning circulation based on the MOC field.
• Examine sea ice cover variability based on the sea ice fraction field.
• Model the distinct responses of ocean properties to freshwater forcing based on the combined salinity and temperature fields.

Strengths

• Data covers a 23-year historical period from 1992 to 2014.
• Variables are provided at a monthly temporal resolution.
• Temperature and potential density fields contain 60 depth levels.
• Global fields have a horizontal resolution of approximately 0.9x1.25 degrees.

Limitations

• Row count and total file size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred from file names.
• Data is from a single model simulation (GrIS), which may limit generalizability.
