CCCma has developed a number of climate models. These are used to study climate change and variability, and to understand the various processes which govern the climate system. They are also used to make quantitative projections of future long-term climate change (given various greenhouse gas and aerosol forcing scenarios), and increasingly to make initialized climate predictions on time scales ranging from seasons to decades. A brief description of these models and their corresponding references can be found by using the following links.

AGCM1	The first generation atmospheric general circulation model.
AGCM2	The second generation atmospheric general circulation model.
AGCM3	The third generation atmospheric general circulation model.
AGCM4 or CanAM4	The fourth generation and current atmospheric general circulation model.
CGCM1	The first generation coupled global climate model.
CGCM2	The second generation coupled global climate model.
CGCM3	The third generation coupled global climate model.
CGCM4 or CanCM4	The fourth generation and current coupled global climate model.

CCCma also participates in several Climate Research Network model development projects including:

CMAM	The Canadian Middle Atmosphere Model.
CRCM	The current Canadian Regional Climate Model.
CanRCM4	The new Canadian Regional Climate Model.
