Multispectral imaging contributions to global land ice measurements from space
Examples of ASTER RGB false-color composites draped over ASTER DTMs. (A) Tasman Glacier, New Zealand. The scene covers approximately 25 x 25 km (B) Llewellyn Glacier, British Columbia. Scale is ∼13 km across the middle of the image and 25 km from bottom (foreground) to top (background). 15m resolution.

3-D atmospheric maps developed from multisensor observations such as the above three data sets. Here is the western Mediterranean (France on left and North Africa on right) with the bottom shown as a landscape image, and atmospheric layers at 8 and 12 km shown in colors with red the warmest and purples coolest. http://rst.gsfc.nasa.gov/Sect16/Sect16_10a.html
