FrankenNAM grids
Every FrankenNAM cycle on this host (window: 3650 days back), newest first. File names follow NOMADS: nam.YYYYMMDD/nam.tCCz.awphysFF.tm00.grib2 and its .idx. The names are NOAA-identical on purpose so that wgrib2, Herbie and curl scripts work unchanged; the files are not NOAA’s.
What these files are. Initialized from the (C−6)Z GFS analysis with a 6 h NAM spin-up. No observations after (C−6)Z. Not produced by NOAA and not affiliated with NOAA.
