CMIP6 Climate Mode Data from Pre-Industrial Control Simulations and Observations

Eight climate mode datasets derived from 23 CMIP6 models' pre-industrial control simulations, each with over 500 years of data. The datasets, covering modes like El Niño and the Atlantic Multidecadal Oscillation, were validated against observational data. They were published by the Australian Ocean Data Network and last updated in July 2026.

Use Cases

• Distinguishing natural climate variability from human-induced change based on the derived climate mode patterns.
• Analyzing the spatial and temporal structure of climate modes like the Interdecadal Pacific Oscillation based on the multi-model simulation data.
• Validating and benchmarking climate model performance based on the comparison with observational data described.
• Improving long-term climate projections based on insights into sub-seasonal to multi-decadal internal variability.

Strengths

• Data is derived from 23 different CMIP6 models, providing a multi-model ensemble.
• Each model simulation contains over 500 years of data, enabling robust statistical analysis.
• Datasets were validated against observational data, revealing broad-scale consistency.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The description notes regional discrepancies and biases in features and amplitudes for some modes.
• Row count is unknown, which may limit suitability assessment.
