HadCM3 Climate Simulation - time varying forcing of major and minor green house gases, anthropogenic sulfur cycle, sulphate aerosols and tropospheric ozone from 1859-2100
Abstract
The AFHb forcings simulation contained in this dataset includes time varying forcing from major and minor greenhouse gases, anthropogenic sulphur cycle with direct plus indirect sulphate aerosol effects, and variations in tropospheric ozone based partly on off-line chemistry calculations from 1859 to 2100. After 1990 the forcing follows the IPCC IS92a emissions scenario.
This is an "all-forcings" experiment designed to investigate the sensitivity of HadCM3 to various forcings, including various minor species specified to give IS92a-like forcing variations); sulphate aerosol direct and indirect forcing (via calibrated delta-albedo); sulfur chemistry without natural DMS and 3D SO2 background emissions, (ie. anthropogenic SO2 emissions surface and high level only) and tropospheric/stratospheric ozone. It is a partner experiment to HadCM3-AFHa which is limited to well mixed green house gas forcings. The HadCM3 model was used by the Hadley Centre to provide input for the IPCC Third Assessment Report.
Data members run for this experiment: aaxzl
Boundary conditions: HADCM3 all-anthropogenic forcings experiment with greenhouse gas forcing as for HadCM3-AFHa (multiple species of greenhouse gases including various minor species specified to give IS92a-like forcing variations); sulphate aerosol direct and indirect forcing (via calibrated delta-albedo); sulfur chemistry without natural DMS and 3D SO2 background emissions, (ie. anthropogenic SO2 emissions surface and high level only) and tropospheric/stratospheric ozone.
Initial conditions: Initialised from year 370 of the HadCM3 control run. (i.e. 2361).

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. |
