Hi all.
I have just used era5_to_int to generate my intermediate WRF files for the first time. I noticed the my met files now have num_metgrid_levels = 138, instead of the usual 38 value. I was wondering if someone can help me figure out how to get num_metgrid_levels = 38 again. Also, is a higher num_metgrid_levels value a good thing when it comes to WRF runs?
 
This is because you process ERA5 model level data, which has 138 vertical levels.

ERA5 pressure level data has 38 vertical levels.

please add -i/--isobaric option to process pressure level data. This meets most users' need.
