ICESat First Light Release: Antarctica in Three Dimensions
|
ICESat's orbit was designed to maximize coverage over the great polar ice
sheets, where ground tracks overlap to create an intricate grid of data
points. The accumulation of these data points in the Southern Hemisphere
results in a new three-dimensional elevation model of Antarctica. ICESat
repeats its orbital pattern every eight days, allowing the GLAS instrument
to measure changes over time in the same location. In order to measure
ice sheet mass balance, the satellite's advanced technology is providing
data on the critically important third dimension, elevation.
