The NGRID feed of HRRR data represents what is provided by NCEP to the NOAA SBN/Noaaport. The headers used can be found here:

So you see the subset of data that is provided...

The direct feed of NCEP products to Unidata/LDM is found on the CONDUIT feedtype.

I am unsure of the HRRR plans for CONDUIT. So I think the answer to your question is yes, FTP/HTTP requests for now.

Is it possible to get the 3D volume of operational HRRR data (either
pressure or native levels) from NCEP via the LDM?

Currently I request like this:


and have this pqact line:

NGRID   ^.*grib2/ncep/HRRR/.*/([0-9]{8})([0-9]{2})00F([0-9]{3})
       FILE    -flush -log

I am getting files, but it looks like just particular levels, not the full
3D volume.  Do I have to use ftp to obtain the full 3D volume?
