The metrics are formulated as frequency-based indices of agreement, thus maintaining the simplicity desired in model development and operational applications, while remedying known shortcomings of common existing skill metrics. User-selectable spatial scales and features of significance allow for the general use of the metrics in variable applications, scales, and observation types.enCopyright 2008 by the American Geophysical Unionlinear features; metric; skill score; sea iceJournal article002013313610.1029/2008GL0350862-s2.0-5884913958217233
