Greenland ice sheet elevation changes

Another example of land applications of ocean altimeter data is its use to measure surface elevation change on the southern Greenland ice sheet. In a study funded by NASA's Polar Program, the ESE, and JPL*, researchers found that the average elevation change above 2000 m elevation from 1978 to 1988 was not significant, contrary to reports that positive ice sheet growth rates suggest increased precipitation due to warmer polar climate.
