METexpress is one component of the METplus verification tool suite, which is created and managed by the Developmental Testbed Center (DTC) and is the official verification tool for NOAA’s Unified Forecast System. Figure 1 (below) shows a graphic of the entire METplus package and how METexpress integrates with the other tools.

In the simplest workflow for verifying model outputs, the model output data and “truth” or observation data are input into the MET software package which outputs statistical information in an ASCII format. That statistical information is then read into and stored in the METdatadb database using the METdbload tool. METexpress allows the user to specify various parameters for the plot they want to create and then queries the database to get the relevant information and creates a plot.
