Line 2: The IGCM is a fast [[Global climate model\|GCM]] based on the primitive-equations baroclinic model of Hoskins and Simmons, which has been converted to run on workstations. Several versions have been developed with representations of the physics. * IGCM1: Portable version of the original spectral dry baroclinic model formulated in sigma-levels, with an option for [[~~Nudging~~data assimilation\|Newtonian relaxation]] and Rayleigh friction, no surface. * IGCM2: Includes simplified moist parameterisations, a cheap "radiation scheme" (i.e. constant tropospheric cooling), a bulk formulation scheme for the boundary layer, fixed surface temperatures and humidity, a uniform vertical diffusion, and can advect tracers. * IGCM3x: Intermediate climate model which includes more sophisticated moist / clouds parameterisations, a radiation scheme with various gas absorbers, and a more realistic surface with an orography and land, sea surface schemes.
