HadCM3 Climate Simulation with Greenhouse Gas and Aerosol Forcings from 1859-2100

A climate model simulation from the Hadley Centre Coupled Model Version 3 (HadCM3) provides time-varying forcing data. The dataset covers a 242-year period from 1859 to 2100, following the IPCC IS92a emissions scenario after 1990. It was produced by the Hadley Centre and contributed to the IPCC Third Assessment Report.

Use Cases

• Analyze the temporal evolution of major and minor greenhouse gas forcing from 1859 to 2100.
• Study the impact of the anthropogenic sulfur cycle and direct plus indirect sulphate aerosol effects on simulated climate.
• Model climate response to variations in tropospheric ozone based on off-line chemistry calculations.
• Benchmark other climate models against this IPCC-report-contributing simulation for the 1859-2100 period.

Strengths

• Simulation spans a 242-year period from 1859 to 2100.
• Model was used as input for the authoritative IPCC Third Assessment Report.
• Includes multiple forcing components: greenhouse gases, sulfur cycle, aerosols, and ozone.

Limitations

• Specific row count, column details, and data resolution are unknown.
• Forcing follows the specific IPCC IS92a emissions scenario, which may not represent all current pathways.
• Data is a model simulation, not direct observational measurements.
