Laser altimeter data obtained over sea-ice during the TIFAX campaign in Aug, 2011
Sea ice surface roughness data were obtained during the TIFAX campaign in Aug, 2011 with a Single Beam Laser Altimeter (SBLA) mounted inside an electromagnetic system (EM-Bird) towed at 10-30 m height above surface by an Airplane (Basler BT-67, Polar-5). A method developed by Hibler (1972) was used...
