Global Low Resolution Sea Ice Drift - Multimission
Listed in NASA Earthdata CMR
Low Resolution Sea Ice Drift product covers both Northern Hemisphere (NH) and Southern Hemisphere (SH), all year round.
Description
Ice motion vectors with a time span of 48 hours are estimated by an advanced cross-correlation method (the Continuous MCC, CMCC) from pairs of passive and active microwave satellite images. Several single-sensor products are available, as well as a merged (multi-sensor) product.
Maps of uncertainties are embedded in the product files. Due to higher atmospheric wetness and sea ice surface melting, it is more challenging to track ice motion during summer. Accordingly, the NH product files distributed between 1 May and 30 September have larger uncertainties and more interpolated vectors.

The same holds for the SH product files between 1 November and 30 March.
