HadCM3 Climate Model Control Run for IPCC Assessments

A control run simulation from the Hadley Centre Coupled Model Version 3 (HadCM3), used to initialize transient climate simulations for the IPCC Third Assessment Report. The simulation uses fixed forcing representative of late nineteenth century atmospheric conditions and was developed by the Hadley Centre. It was initialized and spun up as defined in Johns et al. (2003).

Use Cases

• Analyze climate drift and model stability under fixed late 19th-century forcing conditions.
• Initialize transient coupled model simulations using various emission scenarios as described in the dataset provenance.
• Study the impact of model improvements, such as the sophisticated radiation scheme and new land surface scheme, on baseline climate simulations.

Strengths

• Model developed by the authoritative Hadley Centre and used for the IPCC Third Assessment Report.
• Includes significant improvements over the previous HadCM2 model, such as a more sophisticated radiation scheme and a new land surface scheme.
• The coupled model requires no artificial flux adjustments to prevent excessive climate drift.

Limitations

• The dataset's specific temporal coverage, spatial resolution, and data volume (rows, size) are not provided.
• Simulation uses fixed historical forcing, limiting analysis of dynamic 20th or 21st-century climate drivers.
• The last updated date (2159-01-01) is clearly a placeholder, indicating uncertain metadata freshness.
