HadCM3 is a fully coupled ocean-atmosphere GCM (AOGCM) that was used in UKCP09 for simulating the 17 transient projections of climate change. This means that both the atmospheric and the oceanic processes were included in the modelling, hence providing a realistic representation of the climatological processes.
It was developed at the Met Office Hadley Centre as the next generation to HadCM2 and is one of the models used by the IPCC and in the Coupled Model Intercomparison Project (CMIP3).
- More details about the climate models used in UKCP09 are given in Box 2.1 in the UKCP09 Climate change projections report. A commentary about the strengths and weaknesses of climate models is given in Annex 3.
