MITgcm ECCOv4-TM: Ocean Tracer Simulations for Radiocarbon and CFCs

Model simulation output from the MITgcm ECCOv4-TM system used in a 2023 study by Lester et al. The data contains annual mean fields for Delta-14C, DIC14, DIC, and partial pressures of CFC-11 and CFC-12, derived using transport matrices. Output is provided as Matlab .mat files.

Use Cases

• Validate ocean biogeochemical models based on simulated Delta-14C and DIC fields.
• Analyze temporal changes in anthropogenic tracers based on annual mean pCFC-11 and pCFC-12 concentrations.
• Study ocean circulation and carbon cycling based on transport matrix method outputs.

Strengths

• Data is derived from the ECCOv4 state estimate, a widely used and respected ocean model framework.
• Output includes five distinct annual mean tracer fields (Delta-14C, DIC14, DIC, pCFC-11, pCFC-12) for analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
