Fig 3. Topographic map of the Greenlandice sheet. The contour interval is 100 m. Localice caps and ice domes are shown in green. Ice-free areas are shown in dark gray. (USGS Satellite Image Atlas of Greenland) Figure 3 shows that the contours have the closest spacing along the west ...

The NED is the logical result of the maturation of the long-standing USGS elevation program, which for many years concentrated on production of topographic map quadrangle-based digital elevation models. The NED serves as the elevation layer of , and provides basic elevation information for earth ...
We use the GIMP DEM v2 time-tagged in 2014 to correct for the topographic phase for S134. We map the inward limit of detection of vertical motion, where the glacier first lifts off its bed43. We processed around 1000 interferograms for Petermann, 600 for Ryder, 520 for Steensby and ...
63. Topographic roughness reflects roughness at the greater than 200 m length scale, while the scattering-derived roughness proxy is estimated to reflect roughness at length scales less than 100 m.

The lowest temperature ever recorded in the Northern Hemisphere was recorded in Greenland, near the topographic summit of the Greenland Ice Sheet, on 22 December 1991, when the temperature reached −69.6 °C (−93.3 °F).[84] In Nuuk, the average daily temperature varies over the seasons...
Exchanges between the southeast Greenland shelf and interior seas are driven by winds, eddies and topographic steering. These processes are small scale, intermittent and highly localized. It is likely the eddies and topographic effect enhance mixing of freshwater into the water column in the near sh...
