The case is made that radaraltimeter data can be used to monitor changes in glacier topography related to climate change and surge events. Such changes in snow structure are important as they may influence radaraltimeter returns. It was not until almost 10 years later, however, that theory was turned into reality with the first radaraltimeter missions. The pilots would have seen the same information on their radaraltimeter, but even so at that point the aircraft was still climbing only gently.

The pilots, distracted by the conflicting warnings, did not notice the radaraltimeter after passing through 2,500 feet, according to the accident report.

The satellite carried a radaraltimeter capable of measuring the distance from the satellite to sea surface with a relative precision of about 5 cm. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The radaraltimeter is used to measure height above ground level during landing in commercial and military aircraft. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. A radaraltimeter measured altitude and velocity, feeding data to the rover's flight computer. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The radaraltimeter measures the return power of the radar pulse that's reflected off the land/ocean surface. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Since a radaraltimeter measures distances, height over the ground, and not an absolute altitude, the maps generally encode a series of changes in altitude, not the absolute altitude itself. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The temporal evolution of the reflected radar pulse is interpreted in order to estimate the distance between the radaraltimeter and the reflecting surface; surface irregularities can also be estimated.
