OPeNDAP stands for OPen Network Data Access Protocol; see
http://www.opendap.org

OPeNDAP functionality allows a user to access data remotely, rather
than having to download/copy to a local system.

As an example, to open a file local to your host:

     f = addfile("my.data", "r")

If "my.data" resided elsewhere (not local to your host) and you didn't
want to/couldn't download it, you could say:

     f = addfile("http://fully/qualified/path/to/the/file/my.data", "r")

See the documentation:
     http://www.ncl.ucar.edu/Document/Functions/Built-in/addfile.shtml
     
http://www.ncl.ucar.edu/Document/Functions/Built-in/isfilepresent.shtml

and the example:
