HadCM3 GCM Model Information

Background Information

The experiments performed at the Hadley Centre for the Third Assessment Report use the HadCM3 model, which is the successor to HadCM2 used in the Second Assessment Report.

HadCM3, like HadCM2, has a spatial resolution of 2.5° x 3.75° (latitude by longitude) and the representation produces a grid box resolution of 96 x 73 grid cells. This produces a surface spatial resolution of about 417km x 278 km reducing to 295 x 278km at 45 degrees North and South (comparable to a spectral resolution of T42).
