[from the litho:]
This image illustrates ice sheet elevation and cloud data from ICESat's Geoscience Laser Altimeter
System (GLAS) on its first day of operation, February 20, 2003. On that day, the instrument collected
a 1064 nm wavelength profile across Antarctica: the lower West Antarctic Ice Sheet in the foreground is
separated from the higher East Antarctic Ice Sheet in the background by the steep TransAntarctic Mountains.
The elevation profile (in red) is depicted relative to the Earth's standard ellipsoid with 50x vertical
exaggeration. Data collected across floating sea ice and open water of the adjacent Southern Ocean cannot
be shown at this scale. Clouds of various thicknesses are indicated by colors changing progressively from
light blue (thin clouds) to white (opaque layers). Note that the laser cannot penetrate the thickest
clouds causing gaps in the elevation profile below. The RADARSAT (Canadian Space Agency) mosaic is used
to illustrate the Antarctic continent.
