Summary
Abstract:
Southern Greenland ice sheet elevation change estimates are derived from
SEASAT and GEOSAT radar altimetry data from 1978 to 1988. Data are
confined to 61-72 deg N, 30-50 deg W, above 1700 m elevation. The
addition of GEOSAT Geodetic Mission (GM) data results in twice as many
crossover points and 50% greater coverage than previous studies.
Coverage above 2000 m elevation is improved to 90%, and about 75% of the
area between 1700 m and 2000 m is now covered. Data are in ASCII text
format, available via FTP, and consist of elevation change rate (dH/dt,
cm/year) and corresponding error estimates in 50 km grid cells.

Quality
Refer to Davis et al. 2000 for details of orbit error analysis with
SEASAT and GEOSAT. Comparison with laser dH/dt results and other in-situ
data indicates that a typical error value for elevation change estimates
in a 50 km cell is approximately +/- 2 cm/yr (Davis et al. 2001).
