NASA's Land, Vegetation, and Ice Sensor or "LVIS", is an airborne, wide-swath imaging laser altimeter system that is flown over target areas to collect data on surface topography and 3-D structure. Utilizing a system that includes a 1064 nm-wavelength laser and 3 detectors, the entire time history of the outgoing and return pulses is digitized, allowing unambiguous determination of range and return pulse structure. Combined with aircraft position and attitude knowledge, the sensor produces topographic maps with decimeter accuracy and vertical height and structure measurements of overflown terrain.
These data are from the ICESat-2 summer sea ice campaign operating on NASA's G-V aircraft from July 11-26, 2022 out of Thule, Greenland. The Level 1B data provide the geolocated waveforms and the Level 2 data provide the elevation and height products. To facilitate easier data downloads from this site, Level 1B files are grouped by date and further bundled into 30 HDF5 files per tar.gz file. All Level 2 files have been combined into a single tar.gz file. These data are being hosted temporarily on this site until hosting can be transferred to a permanent location at NSIDC in the coming months.
