Howdy all,
If the data isn't being sent over the SBN yet, you can still get a sneak
peek at what will be sent there on Nomads PARA now:
https://nomads.ncep.noaa.gov/pub/data/nccf/com/para/noaaport/rrfs/
https://nomads.ncep.noaa.gov/pub/data/nccf/com/para/noaaport/refs/
This is of course a subset of the other RRFS/REFS data on Nomads, and
without the .idx files so you need to do a little wgrib2 digging yourself.
We may not know the exact patterns until the data actually starts flowing,
but between that SCN and what data is on PARA now this should be enough for
a strongly educated guess.
For reference, here is the full PARA data set:
https://nomads.ncep.noaa.gov/pub/data/nccf/com/rrfs/para/
https://nomads.ncep.noaa.gov/pub/data/nccf/com/refs/para/
Hope this helps,
-Mike
