Elevation Change of the Southern Greenland Ice Sheet from 1978-88

View Catalog Page

Entry ID

NSIDC-0223

Summary

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).
