Quad-polarimetric transect, recorded in the L-band
Quad-polarimetric transect, recorded in the L-band during the ARCTIC15 campaign, with a length of 200 km, starting at the west coast of Greenland at an altitude of 300 m (left) to the inner part of the ice sheet at an altitude of 2100 m (right). The red line shows the equilibrium line at an altitude of about 1700 m, which separates the ablation zone from the accumulation zone (firn). The polarimetric Pauli-RGB composite image is shown in the center. The polarimetric HH-VV phase difference is shown at the bottom.
