ACCESS1-0 Model Output for CMIP5 Abrupt 4xCO2 Climate Experiment

ACCESS1-0 model output prepared for the CMIP5 abrupt4xCO2 experiment. The experiment imposes an instantaneous quadrupling of atmospheric CO2 concentration and holds it fixed. Output consists of time series per variable in netCDF format at the model's grid spatial resolution, as coordinated by the Coupled Model Intercomparison Project Phase 5.

Use Cases

• Analyzing the transient climate response to a rapid CO2 increase based on the abrupt4xCO2 experiment design.
• Studying Earth system feedbacks and equilibration timescales based on the time series model output.
• Comparing model performance and sensitivity across different modeling realms and variables as part of the CMIP5 framework.

Strengths

• Data follows the standardized CMIP5 experimental protocol and output format, ensuring comparability.
• Output is structured according to the Data Reference Syntax, providing a clear hierarchy for activity, product, institute, model, experiment, and variable.

Limitations

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