Please note that monthly, seasonal and annual mean values of key atmospheric variables over Canada and North America from these GCMs can also be retrieved from the CCCSN web site.
HadCM3 (developed by the Hadley Centre in the UK) is the third version of the coupled atmosphere-ocean model presented in Gordon et al. (2000). Unlike the Canadian model, it does not use surface flux adjustment procedures. The atmospheric component of the model uses 19 levels with a regular horizontal resolution of 2.5° in latitude x 3.75° in longitude, thus consisting of a global 96 x 73 points grid. This corresponds to an approximate resolution of 417 x 278 km at the equator and 295 x 278 km at 45° of latitude (comparable to a T42 spectral resolution). The oceanic component of the model uses 20 vertical levels with a horizontal resolution of 1.25° x 1.25°. Contrary to CGCM2, the HadCM3 model systematically counts 360 days in 12 months of 30 days each.
