Output from 10 global ocean circulation models contributing to the IPCC 4th Assessment Report, focusing on the Indonesian Throughflow and Leeuwin Current region. The dataset includes monthly outputs of 3D zonal and meridional current velocity, wind speed, and stress from the late 1800s to 2100 (or 2200 for some models). It was contributed by the Australian Ocean Data Network and last updated in April 2026.
Use Cases
- Analyzing multi-decadal trends in the Leeuwin Current based on 3D current velocity fields.
- Validating and comparing climate model projections for the East Indian Ocean based on IPCC AR4 outputs.
- Studying the interaction between the Indonesian Throughflow and the Leeuwin Current based on extracted regional model data.
- Investigating changes in wind stress and its influence on ocean circulation in the region over a 200+ year period.
Strengths
- Data spans a long temporal range from the late 1800s to 2100 (or 2200 for some models).
- Includes output from 10 distinct global ocean circulation models, allowing for ensemble analysis.
- Provides full 3-dimensional fields for key oceanographic variables like current velocity and wind stress.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Ocean model horizontal resolutions range from approximately 1 to 2.5 degrees, which is relatively coarse.
