properties
SMMR Scanning Multichannel Microwave Radiometer

RADARSAT (1996-present) and QuikSCAT
(1999-present)
Ice classification between perennial and seasonal
ice zones using RADARSAT and QuikSCAT data.
Could be used by including an age tracer in the
sea ice model.
(Kwok et al., 2004)

RADARSAT Geophysical Processor System
(RGPS) Small-scale kinematics, deformation, and
divergence.
Ice motion is not a continuous field gradients
in the forcing wind field are concentrated in
fractures (discontinuities) and narrow bands of
intense shear (Kwok, 2002).
