[netCDF #MUE-362705]: attribute

Hello,

There isn't an easy way to do this with the tools provided by the netCDF 
library. However, you can use the 'ncrename' utility provided as part of the 
NetCDF Operators (NCO) utility package.  We do not maintain this package, but 
you can download it from the following link:

* https://sourceforge.net/projects/nco/

I hope this helps!
