Sea ice surface roughness data were obtained during the BREA campaign in Apr, 2013 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). A method developed by Hibler (1972) was used to a) isol...
