Hi Daryl! We have long been annoyed when instances like this occur. Heck, RUC2 is still the 'convention' and MRF/AVN titled grids can still be found in deep, dark crevices! I *think* it's just an LDM issue. In fact, the RAP/HRRR upgrade caused some fields to only be recognized by the HDS and not NGRID feed, an issue that I again believe was on the LDM side. Sigh... Sorry to report, but the only one I recognize out of your suspect list is grib2/161/161/#255 Those are MRMS products (http://www.nssl.noaa.gov/projects/mrms/) that we have been receiving for quite some time over the SBN NOAAport NGRID feed.
