Re: regrid script that is a bit buggy

Hi Marston,

My guess is that you defined dimensions for your array variables, but not your scalar
variables.

Everytime you write a variable to a file that you haven't defined the dimensions for,
NCL will assign a new dimension name, starting with "ncl1", and so on. It will give
a different name every time.

To get around this, you need to call filevardef for each of your scalar variables, and use the
special "ncl_scalar" dimension name:

filevardef(ncid, varname,vartype,"ncl_scalar")
where "varname" and "vartype" need to be replaced by the appropriate variable names and types.

This is covered in our FAQ:
