HRES -- Synthetic high-resolution Antarctic bed elevation

HRES is a high-resolution (100m) synthetic bed elevation terrain for the whole Antarctic continent. The synthetic bed surface preserves topographic roughness characteristics of airborne and ground-based ice-penetrating radar data from the Bedmap1 compilation and the ICECAP consortium. Broad-scale features of the Antarctic landscape are incorporated from a lowpass filter of the Bedmap2 bed elevation data. The data are available in NetCDF classic format on a 100m resolution grid in a Polar Stereographic Projection (Central Meridian 0 degrees, Standard Parallel 71 degrees S) with respect to the WGS84 geoid. The 100m grid is 66661 rows by 66661 columns, where the corner of the lower left cell is located at a polar stereographic easting and northing of -3333000 m and -3333000 m, respectively. The value for missing data is -9999.
