Re: How to change global attributes in a netCDF file

I posted message only because " it worked " :-)

FYI: Frequently I use the netCDF operators [NCO]
     as suggested by Kate and Xianglei. In this
     particular instance, NCL was the simplest
     solution.
     
The "w" approach with the addfile function only works
when replacing something of the same size.
