HWT/DTC 2010 Evaluation - Evaluation Techniques

Traditional Verification Techniques

For this collaboration, the DTC will be employing the use of the Model Eval fuation Tools. Specifically, for Traditional Verification, we will be using the Grid-Stat tool, which provides verification statistics for a matched forecast and observation grid. All of the forecast gridpoints in the region of interest are matched to observation gridpoints on the same grid. All the matched gridpoints falling inside a verification masking region defined by the user are used to compute the verification statistics. The Grid-Stat tool functions in much the same way as the Point-Stat tool, except that no interpolation is required because the forecasts and observations are on the same grid. However, the interpolation parameters may be used to perform a smoothing operation on the forecast field prior to verifying it. The output statistics generated by Grid-Stat are largely the same as those generated by Point-Stats.
