Medium Resolution Sea Ice Drift
| IDENTIFICATION |
| Description | Ice motion vectors with a time span of 24 hours are estimated by a maximum cross-correlation method (MCC) on pairs of satellite images. Input data are ~1km Infra Red or Visible data from the AVHRR instrument on board the METOP satellite. |
