Comparison of advanced Arctic Ocean model sea ice fields to satellite derived measurements
Numerical models have proven integral to the study of climate dynamics. Sea ice models are critical to the improvement of general circulation models used to study the global climate. The object of this study is to evaluate a high resolution ice-ocean coupled model by comparing it to derived measurem...
