Greenland April 2022

In April 2022, NASA's LVIS Facility was used to collect data over sections of the Greenland Ice Sheet and surrounding sea ice, supporting University of Kansas/CreSIS radar flights or future sensor design studies. The LVIS-F lidar sensor was used to collect surface elevation and structure information at low (1500’) or medium (23,000’) flight altitudes in the NASA P-3B, operating with 2 LVIS camera sensors and the KU/CReSIS radar sensor. Because of the different flight altitudes, collection parameters of the LVIS lidar and cameras varied (see mission information tables below for further details). Science targets included land and sea ice (from low flight altitudes), Humboldt Glacier and coastal and interior ice surfaces in western Greenland centered on recent ICESat-2 tracks (from medium flight altitudes).
