$ This is an input file for setting user attributes
$ in the netCDF file generated by ww3_ounf.
$
$ This example overrides the default values with
$ attributes based on the CMEMS specification.

$ Fields are specified by the "Tag" name:
META HS
  ename=".vhm0"
  varnm="VHM0"
  long_name="Spectral significant wave height (Hm0)"
  globwave_name=""
  vmin=0.0
  vmax=50.0
  $ an "extra" user attribute (of type "real"):
  pointless_number = 99.9 r
  cell_methods = "time:point"
  
$ Fields can also be specified by their Group(IFI) and Param(IFJ) indices:
$ IFI=2, IFJ=5 is T0m1 field 
META 2 5
  ename=".vt0m1"
  varnm="VT0M1"
  $ attributes can also be specificed with the internal names (varXX)
  varns="sea_surface_wave_mean_period_from_variance_spectral_density_inverse_frequency_moment"
  varnl="Wave period at spectral peak / peak period (T0M1)"
  varng=""

$ Multi-component fields (like wind) can take an extra integer
$ parameter to select the component (1 - 3)
