Output from 10 global ocean general circulation models used for the IPCC Fourth Assessment Report, focusing on the Indonesian Throughflow and Leeuwin Current region. Models provide monthly 3D fields of zonal and meridional current velocity, wind speed, and wind stress. Data spans from the late 1800s to 2100 (or 2200 for some models).
Use Cases
- Analyze multi-decadal trends in zonal and meridional current velocity for the Leeuwin Current.
- Validate model-simulated wind speed and wind stress fields against observational data in the East Indian Ocean.
- Study the projected changes in the 3-dimensional ocean circulation from the late 1800s to 2100.
- Compare the representation of the Indonesian Throughflow across 10 different IPCC AR4 models.
- Assess the impact of model horizontal resolution (1 to 2.5 degrees) on simulated current patterns.
Strengths
- Data spans over 200 years from the late 1800s to 2100/2200.
- Includes output from 10 distinct global ocean circulation models.
- Provides full 3-dimensional monthly fields of key oceanographic variables.
Limitations
- Model horizontal resolution is coarse, ranging from approximately 1 to 2.5 degrees.
- The dataset is a regional subset extracted from global models, not a dedicated high-resolution simulation.
- Specific row counts, file sizes, and data volumes are unknown.
Provenance
- Source
- Output from models contributing to the Intergovernmental Panel on Climate Change (IPCC) 4th Assessment Report.
- Collection Method
- Subset extracted from global general circulation ocean model outputs.
- Time Range
- Late 1800s to 2100 (2200 for some models).
- Freshness
- null
- Geography
- Indonesian Throughflow and Leeuwin Current region in the East Indian Ocean.
