CSIRO-Mk3-6-0 Model Output for CMIP5 RCP4.5 Future Projection (2006-2100)

RCP4.5 is a Representative Concentration Pathway resulting in a radiative forcing of 4.5 W m-2 by 2100. This dataset contains future climate projections from 2006 to 2100, generated by the CSIRO-Mk3-6-0 Earth System model as part of the CMIP5 intercomparison project. Output is provided as time series per variable in netCDF format at the model's native grid spatial resolution.

Use Cases

• Projecting future climate variables based on the RCP4.5 emissions scenario described in the documentation.
• Analyzing time-dependent changes in radiative forcing and related atmospheric components as per the CMIP5 experiment design.
• Comparing model outputs across different Earth System models within the coordinated CMIP5 framework.
• Assessing climate impacts for the IPCC Fifth Assessment Report (AR5) and beyond using the standardized future projection.

Strengths

• Data follows the CMIP5 Data Reference Syntax, ensuring standardized naming and structure for interoperability.
• Projection covers a 95-year future period from 2006 to 2100, providing a long-term climate outlook.
• Experiment is part of the coordinated CMIP5 framework designed for assessment in the IPCC AR5 report.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download from the standard output list.
• Row count and dataset size are unknown, which may limit suitability assessment for specific applications.
• Data may reflect modeling bias inherent to the CSIRO-Mk3-6-0 Earth System model.
