OSI SAF service messages
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.
Replaced OSI-407 on 11 October 2018. Main changes are : use of satellite Metop-B instead of Metop-A, product computed 4 times daily (insead of 2 times previously), individual uncertainties for each ice drift vector.
