HadCM3 Model Output for the 8.2 ka Cooling Event Study

General circulation model output from the HadCM3 model processed for the study of the 8.2 ka cooling event. The data includes variables such as ocean temperature, salinity, precipitation, air temperature, mixed layer depth, sea ice concentration, and meridional overturning circulation strength. The dataset was created under NERC grant NE/L002574/1 and is associated with the 2017 paper by Matero et al.

Use Cases

• Simulating the impact of ice sheet collapse on ocean circulation based on meridional overturning circulation strength data.
• Analyzing regional climate response to a forcing event using the provided air temperature and precipitation variables.
• Studying ocean-atmosphere coupling during a rapid climate change using the co-located ocean and atmosphere model components.
• Validating paleoclimate proxy records against model-simulated variables like ocean temperature and salinity.

Strengths

• Includes seven key climate variables (e.g., ocean temperature, salinity, MOC strength) for a specific paleoclimate event.
• Model resolution is specified: atmosphere at 2.5° x 3.75° and ocean at 1.25° x 1.25°, with described vertical layers.
• Data is processed into a standard, self-describing netCDF4 format for timeseries analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The temporal and spatial coverage of the processed timeseries is not explicitly stated in the description.
