ICESat First Light Release: Antarctica, from Coast to Coast

Title	ICESat First Light Release: Antarctica, from Coast to Coast
Abstract	ICESat's first topographic profiles across the continent reveal the textured surfaces of Antarctic ice sheets in unprecedented detail. The following profile spans the entire Antarctic continent from coast to coast. The transect begins near Wrigley Gulf, crosses the Ross Ice Shelf and central Antarctica, finally tapering off at the Amery Ice Shelf. The high flat area in the center of the continent is called the East Antarctic plateau.

ICESat First Light Release: A Closer View of the Coast

Title	ICESat First Light Release: A Closer View of the Coast
Abstract	Elevation data from ICESat's GLAS instrument is quite detailed, as can be seen in this close-up view of a profile that passes near the Banzare Coast in Antarctica. (The green elevation profile in this animation is exaggerated vertically by a factor of 10x for aesthetic purposes.)

ICESat First Light Release: A Continuous View of Clouds

Title	ICESat First Light Release: A Continuous View of Clouds
Abstract	The GLAS laser system on ICESat is making unique measurements of the heights of clouds and their global distribution. In addition, ICESat can 'see' the distributions of aerosols from sources such as dust storms and forest fires. This animation shows the distribution of cloud layers as seens from the bird's eye perspective of the ICESat spacecraft.

ICESat First Light Release: Antarctica in Three Dimensions

Title	ICESat First Light Release: Antarctica in Three Dimensions
Abstract	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.

ICESat First Light Release: A Global Perspective

Title	ICESat First Light Release: A Global Perspective
Abstract	Criss-crossing the world below at nearly 17,000 miles per hour, ICESat is measuring the Earth from space with unprecedented accuracy. ICESAT measures the Earth by shining pulses of green and infrared light from one of its three onboard lasers. Although the major goal of ICESAT's mission is to observe ice near the poles, the satellite takes measurements continuously around the entire globe, providing valuable information about our planet's clouds, oceans, mountains, forests, and fields.

ICESat First Light Release: From Sea Ice to Ice Streams

Title	ICESat First Light Release: From Sea Ice to Ice Streams
Abstract	The following profile shows the dramatic change in elevation from coastal Antarctica, which is covered in sea ice for most of the year, to the center of the continent. It starts near the Amundsen Sea and travels inward, ending over the West Antarctic Ice Streams where we get a look at this dynamic portion of the polar landscape. (The green elevation profile in this animation is exaggerated vertically by a factor of 10x.)

Title	ICESat Lithograph
Abstract	This still image was generated to be printed as a lithograph for public distribution. [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 Earthandapos;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.
