1) Replacement of the standard BMNG Antarctica by use of a colorized version of the high quality MODIS Mosaic of Antarctica by Terry Haran and Ted Scambos (NSIDC)
2) Fix of Southern Hemisphere sea floor topography errors (GEBCO vesion 1.02, and bug in my code)
3) Fix of Arctic 80N-90N land mask inconsistencies between the MOD12Q1 and GEBCO sea floor topography. Remaining 80N-90N inconsistencies are due to the fact that there are no MOD09A1 land surface reflectances in this area and it was painted with permanent snow in BMNG during all months.
I'm excited for the new dataset! It isn't mentioned, but I hope that they fix the hillshading in southern Crete.
