First, apologies if this is not the correct list; if I should direct this
question elsewhere, please let me know.

Up until this week, we had been ingesting NAM212 girds (40km resolution) using
the pattern:
HDS|CONDUIT ((/mNAM|/mNMM).*#212|prod/nam.*awip3d)
We received the grids for 0-84 hours; however starting Wednesday or Thursday,
this was truncated to 60 hours on 00Z/12Z runs and 48 hours on 06Z/18Z runs.
I'm unable to find any documentation of:
a) Whether this is a permanent change (my guess would be yes) and
b) If there is a similar replacement or upgrade that goes out to 84 hours.
We are seeking answers to both of these questions.
(As a side note, I noticed we may have a problem with receiving data on the
CONDUIT feed - these charts to do not look good -
http://www.unidata.ucar.edu/cgi-bin/rtstats/iddstats_nc?CONDUIT+twister2.sbs.ohio-state.edu
)
Using notifyme on the CONDUIT feed, I found a product awip3d78 that does
provide grids to 84 hours -- however, I'm unsure of the NAM product with which
these grids are associated. What is the best way to determine this?
This page: http://www.nco.ncep.noaa.gov/pmb/products/nam/ seems woefully out
of date (hasn't been updated since Oct 2011).
Thanks in advance for any assistance or guidance,
