CESM2 AGrIS: Ocean Climate Simulation Output for 1992-2014

Historical output from one of four CESM2 simulations exploring the impacts of Greenlandic and Antarctic freshwater discharge on the Southern Ocean. The data contains primary model output variables for investigating anthropogenic ocean heat and carbon content, sea ice fraction, and meridional overturning circulation from January 1992 to December 2014. Tessa Gorte from the University of Colorado Boulder generated this data using the CESM2 model under historical CMIP6 forcing.

Use Cases

• Analyze the response of ocean heat content to freshwater discharge based on the temperature and salinity fields.
• Model anthropogenic carbon uptake in the ocean based on the dissolved inorganic carbon (DIC) fields.
• Study changes in meridional overturning circulation patterns based on the MOC field.
• Investigate sea ice extent and variability based on the sea ice fraction field.

Strengths

• Covers a 23-year historical period from 1992 to 2014, providing a multi-decadal climate signal.
• Contains six primary physical oceanographic variables (temperature, salinity, DIC, DIC_ALT_CO2, MOC, sea ice fraction) needed for key climate analyses.
• Offers global coverage with a horizontal resolution of approximately 0.9x1.25 degrees and monthly temporal resolution.
• Temperature and salinity variables contain 60 depth levels, providing detailed vertical structure.

Limitations

• Description metadata is limited; actual data quality, file formats, and size require manual inspection after download.
• Row count and sample data are unknown, which may limit suitability assessment for specific analytical methods.
• Column-level documentation is absent; field semantics and units must be inferred from the file names or external model documentation.
