Measurements of Radar Backscatter from Arctic Sea Ice in the Summer.
Measurements of radar backscatter from sea ice located near Svalbarb and Greenland were made during the summer of 1980 as part of Project YMER. These data were acquired using the University of Kansas helicopter-borne microwave active spectrometer (HELOSCAT II) which operated over a frequency range o...
