•The Antarctic sea ice cover is generally stable but some
areas are largely varying.
•The ice cover at the Bellingshausen/Amundsen Seas is
declining rapidly but much of
the decline is compensated by increases in the ice cover at the Ross Sea.
•The ice cover in 2001 and 2002 are very different not
only in the B/A region but
at the entire hemisphere.
•AMSR is an excellent successor to SSM/I.
•Advantages of AMSR includes: (a) More accurate ice
concentration and better
definition of ice edges – because of higher resolution and more frequency channels; (b) Wider swath and smaller gap
around the North Pole; (c)
Improved masking of ice free ocean; and (d) Improved masking of ice free land/ocean boundaries.
•Some disagreements between sensors are apparent but may
be largely due to resolution
differences and side lobe effects.
•Co-registered and coincident AMSR and MODIS data in
tandem will provide
complementary and more accurate information about the ice cover AMSR can be used to assess the accuracy of historical
passive microwave data on sea
•The validation of sea ice products from satellite data
is very important
