-----------------
NCL tells you what parameter table it is using
as part of each variable's attributes:
parameter_table_version : 2
parameter_number : 31
EG:
Variable: f (file variable)
filename: cy.00.bin
path: cy.00.bin
file global attributes:
dimensions:
forecast_time0 = 27
gridx_213 = 85
gridy_213 = 129
forecast_time3 = 3
forecast_time4 = 3
forecast_time5 = 13
forecast_time6 = 12
forecast_time7 = 6
variables:
float WDIR_213_HTGL ( forecast_time0, gridx_213, gridy_213 )
sub_center : NWS Meteorological Development Laboratory
center : US National Weather Service - NCEP (WMC)
long_name : Wind direction
units : deg
_FillValue : -999
coordinates : gridlat_213 gridlon_213
level_indicator : 105
grid_number : 213
parameter_table_version : 2 <***************NOTE
parameter_number : 31 <***************NOTE
model : MESO ETA Model
level : 10
initial_time : 07/06/2006 (00:00)

Looks to me like NCL is handling the file correctly.
