Global Low Resolution Sea Ice Drift

IDENTIFICATION
DescriptionIce motion vectors with a time span of 48 hours are estimated by an advanced cross-correlation method (the Continuous MCC, CMCC) on pairs of satellite images. Several single-sensor products are available, along with a merged (multi-sensor) dataset.
