Dataset
HadCM3 Climate Simulation - all natural and anthropogenic forcing experiment (Ensemble element 2).
Abstract
The HadCM3-ALL2 dataset includes time varying forcing from major and minor greenhouse gases, anthropogenic sulfur cycle with direct and indirect sulphate aerosol effects, and variations in tropospheric and stratospheric ozone based partly on off-line chemistry calculations broadly consistent with the IPCC IS95a emission scenario from 1859 to 2002 as well as changes in total solar irradiance and volcanic aerosol. This dataset is the second ensemble member for the HadCM3-ALL ensemble.
The HadCM3-ALL experiment was designed to simulate the combined of all natural and anthropogenic forcings supported by the HadCM3 model.The forcings are based upon historical observations as defined in the IPCC IS95a emission 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: ['acabc', 'acabd', 'acabe', 'acabf', 'acabg', 'acabh', 'acbnk']
Boundary conditions: The HadCM3-ALL2 simulation includes time varying forcing from major and minor greenhouse gases, anthropogenic sulfur cycle with direct and indirect sulphate aerosol effects, and variations in tropospheric and stratospheric ozone based partly on off-line chemistry calculations broadly consistent with the IPCC IS95a emission scenario from 1859 to 2002 as well as changes in total solar irradiance from Lean, et. al. (1995) and changes in volcanic aerosol from Sato et al. (1993).

Initial conditions: The second element of the HadCM3-ALL ensemble was initialised with the December 1959 conditions from the HadCM3 control run (HadCM3-ctrl).

Process overview
| 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. |
