Description
Gridded average height-change rates for Antarctic ice shelves at ~27-km spatial resolution. These rates were derived from a polynomial fit to 18 years (1994-2012) of continuous satellite radar-altimeter measurements of changes in ice-shelf surface height [European Space Agency (ESA) ERS-1, ERS-2 and Envisat missions]. The rates have been corrected for ocean tides, atmospheric pressure (inverse barometer), regional sea-level trends, and surface scattering variation. The data are available in two file formats (HDF5 and ASCII). For full description see included README.txt file.
