[ncl-talk] reading files hosted online

Thu Jun 15 08:37:02 MDT 2023

Jayant, yes, you can open a remote file with the addfile function, but only
if the file is served by an OPeNDAP server.  Your current error message
specifically means "file not found", which could mean either a mistake in
your filename string, or the remote host is not an OPeNDAP server.  Ignore
the part about a SCAN error.  That is merely some internal diagnostics
about the remote file error.

First ensure that the remote is really an OPeNDAP server.  Then check your
filename string outside of NCL, with *ncdump -h "filename"* on the linux
command line.  Read more about remote file access in example 4 on the
addfile function page, on the NCL website.
