In this project we have produced co-registered datasets of laser scanner and ENVISAT ASAR AP data. A comparison of ENVISAT ASAR Alternate Polarization (AP) mode (HH+VV) backscatter coefficient values and polarization ratios with ice freeboard height measured with the KMS laser scanner is made. The CRYOVEX-2003 dataset of 11 April 2003 was used here. The laser scanner data and the ASAR AP data were collected with a time difference of less than 1 hour. The dataset contains many wide and clear thin ice areas between large multi-year ice floes. The main result of the comparison is that a rough relation between the ASAR signal and the laser freeboard measurements is found.
