HadGEM1 (abbreviation for ''Hadley Centre Global Environmental Model, version 1'') is a coupled
climate model
Numerical climate models use quantitative methods to simulate the interactions of the important drivers of climate, including atmosphere, oceans, land surface and ice. They are used for a variety of purposes from study of the dynamics of the c ...

on
climate change
In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to ...
. It represents a significant scientific advance on its predecessor,
HadCM3
HadCM3 (abbreviation for ''Hadley Centre Coupled Model, version 3'') is a coupled atmosphere-ocean general circulation model (AOGCM) developed at the Hadley Centre in the United Kingdom. It was one of the major models used in the IPCC Third Asse ...
. HadGEM1 also provides a basis for further development of models, particularly involving enhanced resolution and full Earth System modelling.
