Description
Time series of height change averages for individual ice shelves, with respect to the start of 1994, at three-month time steps. These time series were derived from 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 time series have been corrected for ocean tides, atmospheric pressure (inverse barometer), regional sea-level trends, and surface scattering variation. The data are available in ASCII (CSV) file format. For full description see included README.txt file.
