Overview of Drifter Data

Overview of Drifter Data#

This page summarizes skill scores comparing simulated particles in the ocean models with in situ drifters. See details describing drifter simulations and metrics here.

The area-based skill score distinguishes between models much more than the separate distance skill score. For the area-based skill score, results show that model skill is similar for CIOFS hindcast and CIOFS fresh below the influence of freshwater (15m and 40m depth) but improved in CIOFS fresh above that (1m, 5m, 7.5m).
