Zusammenfassung |
An algorithm for computing ice drift from pairs of synthetic aperture radar (SAR)
images covering a common area has been developed at FMI. The algorithm has been developed
based on the C-band SAR data over the Baltic Sea. It is based on phase correlation in two
scales (coarse and fine) with some additional constraints. The algorithm has been
running operationally in the Baltic Sea from the beginning of 2011, using
Radarsat-1 ScanSAR wide mode and Envisat ASAR wide swath mode data. The resulting
ice drift fields are publicly available as part of the
MyOcean EC project. The SAR-based
ice drift vectors have been compared to the drift vectors from drifter buoys in the
Baltic Sea during the first operational season, and also these validation results are shown
in this paper. Also some navigationally useful sea ice quantities, which can be derived from ice
drift vector fields, are presented. |
