2. ICESat-2 - Wikipedia

   en.wikipedia.org/wiki/ICESat-2

   Advanced Topographic Laser Altimeter System ICESat-2 ( Ice, Cloud, and Land Elevation Satellite 2 ), part of NASA 's Earth Observing System , is a satellite mission for measuring ice sheet elevation and sea ice thickness , as well as land topography , vegetation characteristics, and clouds. [ 9 ]

3. Bathymetry - Wikipedia

   en.wikipedia.org/wiki/Bathymetry

   The Advanced Topographic Laser Altimeter System (ATLAS) on NASA's Ice, Cloud, and land Elevation Satellite 2 (ICESat-2) is a photon-counting lidar that uses the return time of laser light pulses from the Earth's surface to calculate altitude of the surface. ICESat-2 measurements can be combined with ship-based sonar data to fill in gaps and ...

4. Underwater exploration - Wikipedia

   This has allowed areas where it is too shallow for most vessels to safely access to be bathymetrically mapped. The potential depth that ICESat-2’s Advanced Topographic Laser Altimeter System (ATLASA) can reach is 38 m in optimum conditions. [13] A magnetometer is an instrument that measures magnetic field or magnetic dipole moment. They are ...

   Flooding, whether from rivers overflowing their banks or in coastal regions, is among the most costly natural disasters. Altimetry data from the SWOT mission will make it possible to measure the 3-dimensional shape of flood waves, track floodwater levels, and improve measurements of local topographic details in floodplains.

6. ICESat - Wikipedia

   en.wikipedia.org/wiki/ICESat

   The GLAS lasers emit infrared and visible laser pulses at 1064- and 532-nm wavelengths. As ICESat orbited, GLAS produced a series of approximately 70 m (230 ft) diameter laser spots that were separated by nearly 170 m (560 ft) along the spacecraft's ground track. During the commissioning phase of the mission, the ICESat was placed into an orbit ...

   It operated as an altimeter until a portion of the laser reached end-of-life in June 2001. The instrument then functioned as a radiometer until October 2006. [12] High resolution topographic map of Mars based on the Mars Global Surveyor laser altimeter research led by Maria Zuber and David Smith. North is at the top.
