A Data Fusion Algorithm for Mapping Sea-Ice Concentrations from Special Sensor Microwave/Imager Data
Ice charts from the U.S. National Ice Center are used to evaluate published algorithms for generating sea-ice concentrations from SSM/I data.

Summary: | Ice charts from the U.S. National Ice Center are used to evaluate published algorithms for generating sea-ice concentrations from SSM/I data. The same ice charts, in a form that includes information derived from RADARSAT, OLS and AVHRR data, are used in an operational algorithm that effectively tunes a hybrid of the Bootstrap and NASA team algorithms and principal components of the SSM/I data to the time and region associated with the ice chart. This "tuned" algorithm is then used to interpolate ice concentrations elsewhere in the ice chart where no cloud-free, high resolution visible, infrared or active microwave satellite data are available. The algorithm is designed to operate in near real time to assist the ice analysts in their otherwise manually-intensive task of coupling ice charts for vessels operation in ice infested waters. |
