GRIB2 via manual download

[Dadoof]

Hello there fine folks,

So, I noticed that an update was made some time ago to handle the use of opendata as initial conditions;

[src/ai_models/inputs/opendata.py]
195 | # Fix grib2/eccodes bug
196 |  
197 | opendata = FieldArray([NewMetadataField(f, levelist=None) for f in opendata])

I think if a person wanted to download the opendata grib2 file themselves, and then use it with the '--file' option (as in: ai-models --lead-time 360 --input file --file 20250331120000-0h-oper-fc.grib2 --assets assets fourcastnetv2-small), that same 'FieldArray' piece would be needed for the --file option.

I am unsure if I have this correct, and would welcome your insights on this.

Hello there,

As near as I can tell: the situation described above is still in place. If someone downloads a file, and tries to use the '--input file' option, this error results:

ValueError: operands could not be broadcast together with shapes (57,721,1440) (1,73,1,1)

This happens if I use grib2 or grib1 data.

As opendata is provided in a different grid and format, some preprocessing format will be needed.
