Thanks Mark - I've just cross posted to the UKHAS group.

The GFS model
will undergo physics upgrades at that time. The output
formats should remain the same, but the directory structure
will apparently change as per the notice. Here's what a
current URL looks like:
I assume the
tail end would change from 0600/ to 06/00/ on the 12th. The
0.5 deg and 1.0 deg files should still be available, as there
are many users.
the data from the https server (and perhaps other NOAA model
data servers) will have to change their pulls in a turnkey
fashion during the 12Z cycle.
I don't know
if any of the HABHUB crew is on this email list or not.
Hopefully someone can get word to a contact there.

Just to add some interest to the GPSL launch, it
looks like the GFS forecast that everyone uses for
prediction software is getting a major upgrade the
Wednesday before. The announcement is shown below. I
am a little confused on exactly what is happening to
the existing files (0.5 and 1.0 degree) that most
systems use. Since there is a new directory structure
it would be nice if both systems could be up for a
while but it doesn't sound like that is in the cards.
The pessimist in me says we should all be prepared
for none of the prediction software working Friday or
Saturday. The best and most likely case is everyone
will get the software converted over with a little
down time on Wednesday. I plan on working on mine so
it is ready but will be traveling on Wednesday so it
might be interesting.
If any of you have contacts at Hahhub or any of the
other prediction systems it would be great to hear
Mark Conner, if you have any insight it would be
great to hear that as well.

from gfs.YYYYMMDDCC/. Data will not be
* Grib filter for the parallel GFSv15 0.25
deg output is now on nomads.ncep.noaa.gov
