Hi Jennifer,<br>
<br>
I imagine that I am speaking for everyone in ESG in saying that your
clear and constructive comments have been MOST HELPFUL!<br>

and CMIP5 data, I can say that wget is a fine tool to rely on at
the core of the workflow. Unfortunately, the step up in complexity
from CMIP3 to CMIP5 and the switch from FTP to HTTP trashed the
elegant use of wget. No amount of customized wrapper software,
browser interfaces, or pre-packaged tools like DML fixes that
problem.

<div>At the moment, the burden on the user is embarrassingly high.
It's so easy to suggest that the user should "filter to remove
what is not required" from a downloaded script, but the actual
pratice of doing that in a timely and automated and distributed
way is NOT simple! And if the solution to my problem of filling
in the gaps in my incomplete collection is to go back to
clicking in my browser and do the whole thing over again but
make my filters smarter by looking for what's already been
acquired or what has a new version number … this is
unacceptable. The filtering must be a server-side responsibility
and the interface must be accessible by automated scripts. Make
it so! </div>
<div><br>
</div>
<div>By the way, the version number is a piece of metadata that is
not in the downloaded files or the gateway's search criteria. It
appears in the wget script as part of the path in the file's
http location, but the path is not preserved after the wget is
complete, so it is effectively lost after the download is done.
I guess the file's date stamp would be the only way to know if
the version number of the data file in question has been
changed, but I'm not going to write that check into my filtering
scripts. </div>
