W.: Sea surface height determination in the Arctic Ocean from ERS altimetry
[1] Accurate sea surface height measurements have been extracted from ERS altimeter data in sea ice–covered regions for the first time. The data have been used to construct a mean sea surface of the Arctic Ocean between the latitudes of 60N and 81.5N based on 4 years of ERS-2 data. An RMS value for...
