Developing a State-of-the-Art Verification Toolkit
Forecasts get better each year, but there is always room for improvement. They must be scrutinized for what went right and, more importantly, what didn’t. Verification, the testing and evaluation process of a forecast, is a critical component of improvement. Evaluation findings provide needed information to end users, supplying them with objective data about the quality or accuracy of the forecasts.
The DTC verification team supports testing and evaluation activities by providing the open source Model Evaluation Tools (MET) software package and support. It provides the capability to do traditional, spatial, or tropical cyclone verification. Enhancements in this package now give users more flexibility and control over particular conditions they want to test and evaluate. The user community, which includes university researchers, government agencies and operational centers, relies on this technology and service, and is growing nationally and internationally. MET was recently included in a Docker container to lower the learning curve for new users.
For more information and to download the software (and container), please see the MET homepage. Questions about verification methods and MET: firstname.lastname@example.org
