[ncl-talk] Ignore Fatal error question

[Mary Haley]

Barry,

If you are trying to use the reassignment operator to try to force a
variable on a file to potentially be a different type and/or size, I don't
think this is going to work.

For starters, a NetCDF file has very specific definitions for all its
variables, include their sizes, types, and coordinate arrays, if any.

While you can overwrite a variable on a file with new values, I don't think
you can completely redefine the variable on the file with different
dimensions and/or type.

You said that NCL does not like the command. What does mean? Did you get an
error?

Also, what does the L_OBS variable on the file look like, compared to
what l_obs_new
looks like?

Use printVarSummary to look at your data!

  printVarSummary(l_obs_new)
  printVarSummary(f-> L_OBS)
