Abstract

The SRESA2 simulation contained in this dataset includes forcings of green house gases (including methane) that are consistent with historical levels and the future IPCC SRESA2 scenario, sulfur (direct and indirect forcing, sulphur chemistry without natural DMS and SO2 background emissions; anthropogenic SO2 emissions from surface and high level only) and tropospheric/stratospheric ozone.

This experiment produced model outputs reflecting the SRES-A2 emissions scenario . The HadCM3 model was used by the Hadley Centre to provide input for the IPCC Third Assessment Report.

Data members run for this experiment: ['aaxzi', 'abwad', 'abwae']

Boundary conditions: All anthropogenic forcing from multiple species of greenhouse gases as defined for the IPCC SRESA2 emissions scenario, sulfur (direct and indirect forcing, sulphur chemistry without natural DMS and SO2 background emissions; anthropogenic SO2 emissions from surface and high level only) and tropospheric/stratospheric ozone.

Initial conditions: All initialisation runs are from the historic anthropogenic forcing ensemble runs of HadCM3. Element 1 (run: aaxzi) used run: aaxzz (date - 1989-12-01) for initialisation. Element 2 (run: abwad) used run: abqzd (date - 1989-12-01) for initialisation. Element 3 (run: abwae) used run: abqzd (date - 1989-12-01) for initialisation.

More detailed metadata on the model configuration and parameters is available in XML format.

Title	Hadley Centre Hadley Centre Coupled Model Version 3
Abstract	The Hadley Centre Hadley Centre Coupled Model Version 3 was developed from the earlier HadCM2 model in the period 1997-2000. Various improvements were applied to the 19 level atmosphere model and the 20 level ocean model and as a result the model requires no artificial flux adjustments to prevent excessive climate drift. The atmosphere and ocean exchange information once per day, heat and water fluxes being conserved exactly. The main differences from the previous HadCM2 model are a significantly more sophisticated radiation scheme; the inclusion of the direct impact of convection on momentum; and the inclusion of a new land surface scheme that includes a better representation of evaporation, freezing and melting of soil moisture. It improved on the resolution available from previous Hadley Centre models and included support for interactive couplings between the atmosphere and ocean and the biosphere, atmospheric chemistry, the sulphur cycle and atmospheric aerosols. The HadCM3 model was used by the Hadley Centre to provide input for the IPCC Third Assessment Report.
