In 1991, NASA initiated an airborne remote sensing program in conjunction with coordinated surface measurements for determining the mass balance of the Greenland ice sheet, which plays in important role in the rise of global sea level. Starting in 1995, NASA combined various efforts on the mass-balance studies into a coordinated effort called Program in Arctic Regional Climate Assessment (PARCA). The University of Kansas has been participating in this program to make airborne ice thickness measurements using coherent radar depth sounders. Since 1993, the authors have collected a large volume of ice-thickness data over the ice sheet. They have demonstrated that coherent radars can acquire ice thickness and internal structure data over the thickest part of the ice sheet and outlet glaciers located around the ice margin.
