ACCESS1-3 Model Output for CMIP5 RCP4.5 Future Climate Projection (2006-2100)

RCP4.5 is a future projection experiment from the CMIP5 - Coupled Model Intercomparison Project Phase 5, providing a framework for coordinated climate change experiments. The dataset contains time series output from the ACCESS1-3 Earth System model for the period 2006-2100, forced by the RCP4.5 concentration pathway. Data is provided by the Australian Ocean Data Network 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 experiment.
• Analyzing time-dependent changes in radiative forcing and related atmospheric components as outlined in the RCP definition.
• Comparing model output against other CMIP5 experiments for coordinated climate model intercomparison studies.
• Assessing climate impacts for the IPCC Fifth Assessment Report (AR5) and beyond, as referenced in the project description.

Strengths

• Data is part of the standardized CMIP5 framework, a major coordinated international climate modeling effort.
• Covers a 95-year future projection period from 2006 to 2100.
• Output follows a defined Data Reference Syntax and is documented via CMIP5 standard output and experiment design documents.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
