! field is interpolated from MODIS FPAR, and the LU_INDEX/LANDUSEF fields
! are interpolated from 21-class MODIS.

That script was updated. Please try plotgrids_new.ncl from the same github directory.
https://github.com/NCAR/WPS/blob/master/util/plotgrids_new.ncl

Also consider updating to the current NCL version, 6.6.2.
