missing lead hours in output stat file name

[JiliDong-NOAA]

I am using metplus to generate ensemble stats and found out the output stats file name has no lead hours, e.g.
ensemble_stat_rrfs_ADPSFC_NDAS_20210504_180000V.stat

The deterministic stats do have the lead hours in the file name, e,g,:
point_stat_RRFS_CLOUD_HWT_NDAS_ADPSFC_360000L_20210504_120000V.stat

I wonder if there are parameters/options I should change to have it back for ensemble stats.

Thanks for help.

Hi Jili,

And thank you for your question. Ensemble-Stat does not list the lead hours by default, instead using the valid time. In the MET user's guide, there's the following explanation for this default choice:

The output STAT file is named using the following naming convention:

ensemble_stat_PREFIX_YYYYMMDD_HHMMSSV.stat where PREFIX indicates the user-defined output prefix and YYYYMMDD_HHMMSSV indicates the forecast valid time. Note that the forecast lead time is not included in the output file names since it would not be well-defined for time-lagged ensembles.

If it's important that you have the lead time in the file name, you can utilize the "output_prefix" option to customize the file names as needed. Information on that option is here.

I hope this helps answer your question; if it has, please mark this as the answer and I'll go ahead and lock the discussion thread. If you need more clarification on this question, please reply as needed.

Thanks for the explanation. That makes sense. I am able to get lead hours by including them in output_prefix. Will mark this as answer and thanks again for help!
