What upstream mask product did you use? Greenland (GIMP), Antarctica (Bedmachine 2), Arctic (Ice mask ESA CCI Land Cover User Tool (v.3.10)). By default, it is the Ice mask ESA CCI Land Cover User Tool (v.3.10)) which is used as it provides information also over Alps, Alaska, Patagonia, Himalaya, ... where MAR is also used.
Reason for using this mask: the MAR pre-processing tool is able to use these masks. Having a same data set on a common grid for both hemisphere will be the best
Effort required by you if upstream product changed (to a community standard): having a Netcdf file with lat/lon of each pixel is the best for me and I can easily adapt the MAR pre-processing tool.
Type: raster
Resolution if raster: 1km
Projection information: EPSG 3031 for Antarctica and EPSG 3413 for Greenland/Arctic but the mask does not need to be on these grids.
