A scheme is presented for thermo-mechanical coupling of a snow/firn layer with low spatial but high temporal resolution, on top of an ice sheet with high spatial but low temporal resolution. Central to the thermal coupling is gridpoints that are shared between the two models. Initial results are presented, based on a new implementation of the snow/firn layer in the GISS climate model.
