Matt, The 32km Native ETA grid is not one that is broadcast via NOAAport- so therefore not one provided via the IDD. That means that the normal universities which have archives of the IDD are not going to be able to help most likely. The grid 212 40km and grid 211 80km CONUS grids are available on the IDD so some sites probably have them on archive. The only source I know of for the 32km native grid in real time is the ftp.ncep.noaa.gov ftp server... but this is not an archive. Possibly NCDC would be the place to go. The Native 32km, 50 level grid is huge- approximately 65 megabytes per forecast hour output (about 1 GB per model run), so if you need a substantial period of data, it will be a significant amount of data. Gempak is capable of decoding the GRIB source into a Gempak grid file for analysis. Depending on what you need to look at, the 40km grids may be acceptable for analyzing the meteorological conditions, since they are just an interpolation from the native grid; however, if you are trying to analyze model performance and sensitivity then you might need the native grid.
