land coupling: (glc_2_lnd and lnd_2_glc) the surface mass balance (SMB) between the ice sheet and the atmosphere is calculated in the land model. The “glc_2_lnd” coupling passes the necessary data to and from that calculation. The land ice passes elevation of the ice sheet in a flexible number of topography classes (10 in the example below) to the SMB routine in the land model.
sea-ice coupling: (glc_2_ice): icebergs. Icebergs form from the ice sheets but are then advected by the sea-ice model.
