Re: how to copy global attributes from one netCDF file to another

Hi Basit,

first you have to read all global attributes from your input file and
afterwards write it to the new file:

begin

;-- open files
   f = addfile("input_data.nc","r") ;-- input data file

   system("rm -rf global_att_test.nc") ;-- delete file
   g = addfile("global_att_test.nc","c") ;-- create new
netcdf file

   global_attnames = getvaratts(f) ;-- retrieve the
global attributes from input file

   do i=0,dimsizes(global_attnames)-1
      print(f@$global_attnames(i)$) ;-- print global
attribute contents
      g@$global_attnames(i)$ = f@$global_attnames(i)$ ;-- write global
attributes to new file
   end do

end

Bye,
Karin
