I don't know whether you have the NCAR Command Language (NCL) which is
available with NCAR Graphics release 4.1, but the following script would
create a new file and not copy the variables you want to delete.
BTW, the following script won't work with NCL 4.0 since the '$' syntax was added
at release 4.0.1. Also the following script copies all of the variables
attributes and coordinate variables too.
begin
variables_to_delete = (/"var1","var2","var3"/)
in_file = addfile("oldfile.nc","r")
out_file = addfile("newfile.nc","c")
vnames = getfilevarnames(in_file)
do i = 0, dimsizes(vnames)-1
if(.not.any(vnames(i).eq.variables_to_delete)) then
out_file->$vnames(i)$ = in_file->$vnames(i)$
end if
end do
end
