50 # Vtable for GFS pressure-level data from the ncep server.
51 # This version includes fields from the Tropopause and Max Wind levels used by WRF V3.6.1 and later.
52 # NCEP has used multiple definitions of the soil temperature in their output and the Vtable attempts
53 # to account for these possibilities. (Definition changed 14 Jan 2015).

68 # As of mid-2017 the GFS provides two land mask fields in the pressure-level output. WPS uses LANDN if available
69 # and renames it LANDSEA.
70 #
71 # As of WPS V4.1 (April 2019) the default PMSL is changed to MSLET. MSLET is an unsmoothed sea level pressure.
72 # NCEP included MSLET in their GFS files beginning 12z on 10 May 2011 and in their GDAS files at 12z 14 January 2015.
73 # The smoother PRMSL is in all GFS/GDAS pressure files.
74 # For GFS files prior to those dates use PRMSL as shown in the following line:
