It turns out that the server you are using is not up-to-date with respect to the DAP2 spec. It is returning something like this: Dataset { float prmslmsl[ens=1][time=1][lat=1][lon=360]; } gens%2fgens20140123%2fgep_all_12z; when it should be returning this: Dataset { Structure { float prmslmsl[ens=1][time=1][lat=1][lon=360]; } prmslmsl; } gens%2fgens20140123%2fgep_all_12z; I have in the past added hacks to detect this kind of non-conforming servers, but apparently I need to add some additional hacks. Should have fix in a day or so. =Dennis Heimbigner Unidata =Dennis Heimbigner Unidata Ticket Details =================== Ticket ID: ZQX-155900 Department: Support netCDF Priority: Normal Status: Closed
