   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).

Group: 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.
