As long as the model reports 'calculations are correct' the model is behaving satisfactorily in your compilation and run environment. However, note that the ref_021_0144 file was generated by using the GNU compilers. If you use a different compiler such as Intel, you will see a larger maximum error value.
Generating validation tests
To generate additional validation tests to produce your own ref* files, use the namelist switch:
| Panel | ||
|---|---|---|
| ||
LREFGEN=.true., |
With this set, run the model for a short forecast. At the end of the run, a ref_*_* file will be created with the resolution value and the total number of steps in the filename.
The model should not be run for long because this test relies on a linear growth of errors. A 12 hour run is generally recommended, particularly at higher resolutions.
