Land-based ice height change between ICESat and ICESat-2

This map shows changes in Antarctic land ice thickness as measured by the ICESat (2003-2009) and ICESat-2 (2018-) satellites. Thickness is inferred from rising and falling ice-surface height. Areas of decreasing height appear red or orange, and areas of increasing height appear blue. This is a still image from an animation by NASA’s Scientific Visualization Studio.
