 atial Verification of Sea Ice Edges Using Distance-Based Metrics\n\nSea ic
 e models are used to forecast sea ice edges\, which are useful for determi
 ning safe shipping routes. Traditional verification of sea ice models have
  typically relied on grid-point to grid-point comparisons of observations 
 against forecasts\, which ignores spatial structure and leads to a double-
 penalty in assessing forecast skill. Ice edge forecasts are well suited fo
 r spatial verification\, as interest is in where the forecast was wrong\, 
 and by how far. Common spatial verification methods for sea ice edges incl
 ude the Integrated Ice Edge Error (IIEE) and various distance-based metric
 s. For a distance-based metric to be considered a true metric\, it must fu
 lfill four criteria: positivity\, separation\, symmetry\, and the triangle
  inequality. Common distance metrics currently used by the sea ice communi
 ty fail to fulfill the symmetry principle. In this talk\, I will present s
 ome commonly used sea ice edge spatial verification methods\, explain how 
 they are not symmetric\, and conclude by proposing a new method that is sy
 mmetric.\n\nWednesday Nov 06/ 2.30 PM/ Room 934 Burnside Hall\n\n \n\n \n
