10 general circulation ocean models from the IPCC 4th Assessment Report provide monthly outputs of zonal and meridional current velocity, wind speed, and stress. The data covers a subset region encompassing the Indonesian Throughflow and Leeuwin Current in the East Indian Ocean. Outputs span from the late 1800s to 2100 (2200 for some models), with horizontal resolutions ranging from approximately 1 to 2.5 degrees.
Use Cases
- Analyze multi-decadal trends in ocean currents based on monthly velocity outputs.
- Model climate change impacts on regional ocean circulation based on IPCC AR4 projections.
- Study the relationship between wind stress and current velocity in the East Indian Ocean.
- Compare the performance of different ocean models (1-2.5 degree resolution) for the Leeuwin Current region.
- Investigate the dynamics of the Indonesian Throughflow and its downstream effects.
Strengths
- 10 distinct ocean models provide a multi-model ensemble for analysis.
- Long temporal coverage from the late 1800s to 2100 (or 2200) enables study of historical and projected trends.
- Monthly outputs of 3-dimensional fields (current velocity, wind speed, stress) offer detailed temporal resolution.
- Focus on a specific, important oceanographic region (Indonesian Throughflow and Leeuwin Current).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic and temporal bias inherent to the contributing IPCC models.
