Abstract :
Twice-daily backscatter maps constructed from SeaWinds scatterometer data are used to monitor the rapid growth of the 2001 Odden. Scatterometer-only derived parameters are used to discriminate new-ice from open water areas. Validation is performed using RADARSAT and ERS-2 SAR scenes. It is shown that SSM/I derived information not only lag those of the scatterometer by twelve to twenty four hours, but would have told a totally different time evolution of the Odden.
