Old Frequently Asked Questions

Q: Why was the MET written largely in C++ instead of FORTRAN?
A: MET relies upon the object-oriented aspects of C++.

Q: Why is PREPBUFR used?
A: The goal was to initially replicate the capabilities of other existing verification packages and make these capabilities available to both the DTC and the public.

Q: Why is GRIB used?
A: Forecast data from both WRF cores can be processed into GRIB format, and it is a commonly accepted output format for many NWP models.

Q: Is GRIB2 supported?
A: Yes, as of version 5.0.

Q: How does MET differ from the previously mentioned existing verification packages?
A: MET is an actively maintained, evolving software package that is being made freely available to the public through controlled version releases.

Q: How does the MODE tool differ from the Grid-Stat tool?
A: They offer different ways of viewing verification. The Grid-Stat tool provides traditional verification statistics, while MODE provides specialized spatial statistics.

Q: Will the MET work on data in native model coordinates?
A: No - it will not. In the future, we may add options to allow additional model grid coordinate systems.

Q: How do I get help if my questions are not answered in the Users Guide?
A: First, refer to the documentation on this website. If that doesn't answer your question, then email:

Q: Where are the graphics?
A: Currently, very few graphics are included. Further graphics support will be made available in the future on the MET website.

Q: How do I reference the MET Users Guide in publications?
A: Please reference the MET Users Guide (including the version number) as follows:
Developmental Testbed Center, 2018:
MET: Version 8.0 Model Evaluation Tools Users Guide.
