Lineage Généalogie |
This product provides users with a continuous winter (Oct-April) time series of drift vectors over Arctic. These drift vectors are provided on a polar stereographic grid every 31.25 km, over a 3-days overlapping time period. It is a merging of the sea-ice drift vectors retrieved separately using respectively the H and V AMSR-E polarizations channels (from winter 2002-2003) observations. The estimation of sea-ice drift for each one relies on a basic correlation technique applied to the field of the second spatial derivative (Laplacian) of 6.25km resolution composite maps separated by a few days (brightness temperature). |
