I try to read from a netcdf file as above, with version 8.1.0.604 (R2013a), but get an error. Is this a know bug? Is there any workaround? For a local file, or an open thredds server I don't have this problem.

I'm having the same problem. Any help would be appreciated.

I have a similar problem but it gives me this Error. I've used the link several times in google chrome, and in the last weeks I've downloaded the information in ascii format and then I've transformed it to a 3D-matrix. Although I would like to do it directly to my workspace. I'm posting the command line below.
Thank you so much for the help

This will not work at least through R2014a (I do not have a later version to check with). See http://uk.mathworks.com/matlabcentral/answers/248192-problem-with-netcdf-file-downloaded-from-an-opendap-source#answer_195740
