In particular, the different handling of missing values in the interpolation formula leads to differences close to the coasts and ice shelves.  This is demonstrated here using the model bathymetry field and considering only the differences in the missing values in fields produced by MIR and EMOSLIB.

HRES WAM 0.125 degree reduced lat-lon grid

The model bathymetry has been interpolated from the 0.125 degree reduced lat-lon grid target grid to regular lat-lon grids at different resolutions using EMOSLIB and MIR and the number of missing values in the resulting fields compared (the values themselves are not considered here).
