TGLO skill estimates

Skill estimates for the mooring locations were calculated from a simulation lasting one year: summer 2001 to summer 2002. The largest skill is for buoy D, away from the Mississippi, and near the coast. Most of the skill estimates are around, or beneath zero, indicating that the model error is of a similar magnitude to the variance. The first two columns of numbers are the skill for the east-west and north-south velocities. The third column is the skill for speed. This particular model run had no buoyancy forcing, and represents the 'base' model skill, to which future, improved runs will be compared.

All timeseries use the mean of the data for the 'climatology', which produces the lowest skill estimates (see paper on skill linked below). Also, if the timeseries are filtered more, say with a 3-day boxcar, the skill is increased so that 4 to 5 of the skill estimates are positive.
