RE: long_name_mod

["McCann, Mike" <mccann@xxxxxxxxx>]

All,

Thanks to offline help from Steve and Ansley I have a solution:

The long_name_mod attribute should be saved in the file as it may contain potentially useful regridding information.

To disable long_name_mod's appearance on the plot assign the variable form the file to a temp plotting variable, e.g.:

  ! Now read the file and make sample contour plot
  USE foo.nc
  SET REGION/T=1-JAN-2000:31-JAN-2000
  let plot_var = SALINITY_FILT		! New var will not contain long_name_mod attribute
  set var/title="`SALINITY_FILT,return=title`"/units="`SALINITY_FILT,return=units`" plot_var
  FILL plot_var

Hope this helps someone else,
Mike

LET W = i[i=1:3]
LET SALINITY_FILT = CONVOLVEL(SALINITY_HR,W)
SET VAR/TITLE="Filtered Salinity"/UNITS="" SALINITY_FILT
SAVE/CLOBBER/FILE="foo.nc" SALINITY_FILT
SPAWN ncdump -h foo.nc

! Now read the file and make sample contour plot
CANCEL VAR SALINITY_FILT
USE foo.nc
SET REGION/T=1-JAN-2000:31-JAN-2000
FILL SALINITY_FILT



Thanks in advance,
Mike
