CGCM3

The Third Generation Coupled Global Climate Model (CGCM3) is a product of the Canadian Centre for Climate Modelling and Analysis. It updates the earlier Second Generation Coupled Global Climate Model with a new atmospheric component, the oceanic component remaining unchanged. It has been run at two resolutions, the T47 version with a 3.75 degree grid cell size for atmospheric horizontal resolution and 1.85 degree resolution for the oceanic component, and the T63 version has a 2.8 degree atmospheric resolution subdivided into 6 oceanic grid cells.
