Re: writing to a netcdf file

Hi,

Here are a few examples of how to output your data to a netcdf file in NCL.

http://www.ncl.ucar.edu/Applications/o-netcdf.shtml

The methods available depends on how efficient you want your script to be.
The easiest method takes a long time to write data to a netcdf file. Faster
ways require you to predefine your variables before writing them to the
file. It's a bit more coding but helps you to better understand NCL and
netcdf file conventions.

Good luck!
