[conduit] Grid availability

Hello everyone,

I hope you’re staying warm! I have a question for the group. I’d like to know 
the availability of what is on the feed; the UNIDATA list is four years old.

HRRR (grid #187 I believe it is)
NAM (grid #218)
NAM NEST (grid #227)
RAP (grid #130)
Also, does anyone know how big are the files for each run?

Thanks!

Gilbert
