GCMD

Summary

Abstract: The Hadley Centre Coupled Model Version 3 was developed from the earlier HadCM2 model. 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. Momentum fluxes are interpolated between atmosphere and ocean grids so are not conserved precisely, but this non-conservation is not thought to have a significant effect. 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. The HadCM3 model was used by the Hadley Centre to provide input for the IPCC Third Assessment Report. The simulation output contained in this dataset is part of the 2nd QUMP (Quantifying Uncertainty in Model Predictions) Fully Coupled Transient Ensemble. It simulates an emissions scenario with atmospheric CO2 increasing at a compound rate of 1 percent per annum from preindustrial conditions. This run is part of a 17 element control ensemble produced by the QUMP project.
