Use of microwave radar data to interpret physical properties of ice and snow on the Greenland ice sheet
In situ observations of microwave radar backscatter were made at Dye-2 in south-central Greenland in 1993. Simultaneous observations of snow and ice physical properties were also acquired. Early in the season, it was found that 20° backscatter from the snow surface was determined mainly by the snow...
