If you have questions, comments, or problems please use the help@iri link. This page will evolve as we learn more about how Ferret handles data downloads, and your help pointing out problems is much appreciated.
There is a bug in ferret which is corrected in release 6.0 (see notes about "nonstandard calendar axes"). Please upgrade if you are using monthly data.
