Abstract:
Passive microwave radiometry has become a popular tool to derive cloud-independent
sea ice information from remote areas in the Arctic.
A number of different algorithms that derives total ice concentration and multi-year
ice fraction from the Special Sensor Microwave/Imager (SSM/I) instrument
have been published in the open literature.
5 such algorithms have been implemented and carefully adjusted (tie-point adjustment)
in order to allow for direct intercomparison during a two-month winter period in 1993.
Where necessary, the tiepoints are transformed according to the algorithm atmosphere
correction.
Results of the intercomparison includes algorithm stability, and algorithm sensitivity
to various types of geophysical noise and to instrument noise.
