Hi,
re:
> I had previously been using the gfs207 grid for Alaska. However, it hasn't
> updated since August last year. Was it removed,
I know that the 80 km grids were removed from the NOAAPort broadcast some
time ago, and I believe that broadcast of the grid you are referring to was
also
discontinued by the NWS.
re:
> and is there an alternative (coarse 40+ km ) grid I can use instead?
There are three grids that cover Alaska:
NAM Alaska 11km --
NAM Alaska 45km from NOAAPORT --
NAM Alaska 45km from CONDUIT
re:
> And, is there an example of the pqact entry I should use for it?
We use:
#

#
# NAM Alaska 11 km

NGRID ^[LM].S... KWBE ([0-3][0-9])([0-2][0-9]).*NAM_84/#242

re:
> Finally, is there somewhere I can go to see all products available on
> NOAAPORT? Thank you.
We know of no document that details exactly what the NWS is distributing
in NOAAPort. The IDD contents of sever IDD feeds are completely determined
by what is received in NOAAPort, so we don't have any documentation for
them.
Reminder:
LDM users can always see the Product IDs for a feed using the LDM utility
'notifyme'
<as 'ldm'>
notifyme -vl- -f <feed type>
etc.
Cheers,
Tom
