2006: Optimization of a Sea Ice Model Using Basinwide Observations of Arctic Sea Ice Thickness
A stand-alone sea ice model is tuned and validated using satellite-derived, basinwide observations of sea ice thickness, extent, and velocity from the years 1993 to 2001. This is the first time that basin-scale measurements of sea ice thickness have been used for this purpose. The model is based on...
