Short summary
We present an efficient approach for coupling ice sheet and solid Earth models, bringing realistic gravitational and deformational processes into mainstream ice sheet modeling. Earth responses are encoded in precomputed Green’s functions and applied to modeled ice mass change through matrix multiplication. By removing a major computational and technical barrier, the approach could accelerate adoption within the Ice Sheet Model Intercomparison Project (ISMIP) to improve sea level projections.
