Re: I want to change the sort of attributes for a netCDF file

Hi Ehsan,
The order that the attributes are written is opposite to how they are
shown in the netCDF file (or in the output of printVarSummary). For example:

ncl 1> a = addfile("example.nc","c")
ncl 2> var = (/1,2,3,4/)
ncl 3> var!0 = "var"
ncl 4> var&var = var
ncl 5> var_at_att1 = "Attribute 1"
ncl 6> var_at_att2 = "Attribute 2"
ncl 7> var_at_att3 = "Attribute 3"
ncl 8> a->var = var
ncl 9> exit

-/home/>ncdump -h example.nc | less
netcdf what {
dimensions:
         var = 4 ;
variables:
         int var(var) ;
                 var:att3 = "Attribute 3" ;
                 var:att2 = "Attribute 2" ;
                 var:att1 = "Attribute 1" ;

I know of no quick way to alter the order of attributes in a netCDF
file. The only ways I can think of are: by either editing it by hand in
NCL (by using the "w" option of addfiles), or by using the ncatted
netCDF operator and deleting and then recreating the attributes in the
proper order.
