If you have questions, comments, or problems please use the help@iri link.
This page will evolve as we learn more about how NCL handles data downloads,
and your help pointing out problems is much appreciated.
*DODS (a.k.a. OpenDAP) is not necessarily installed in NCL and if OpenDAP is not installed, giving NCL a URL instead of a local
file name will result in a file-not-found error.
In that case, you can use addfile after you download the netcdf file.
