Sea Level Deviation


* Forecast quality is a measure of the expected CCA cross-validation skill. In general terms, these kinds of forecasts are thought to be of useful skill (but poor) skill if the CCA cross-validation value is between 0.3 ~ 0.4. Higher skills correspond to greater expected accuracy of the forecasts. Skill levels greater than 0.4 and 0.6 are thought to be fair and good, respectively, while skill levels greater than 0.7 are thought to be very good.
