| Icing Forecast Verification |
The verification group continues to search for and develop new and better approaches for verification of icing forecasts. Because verification has a critical role to play in the developenment of new forecast products, and because verification of these types is inherently difficult, this research is an important aspect of the forecast development process. In general, the standard verification approaches are based on the direct comparison of the points on a forecast grid to the corresponding points on an observation grid. From these comparisons, for example, the counts of matched and mis-matched forecast-observation pairs can be determined. These pairs then can be used to compute such standard verification statistics as the probability of detection (POD), the False Alarm Ratio (FAR), and the Critical Success Index (CSI). |
