[IDV #WKL-264902]: FNMOC Grib2 file cannot be opened



Hi Kevin,

This has to be put on the TODO list.

Unfortunately, currently the CDM does not support this type of ensemble, nor 
does the IDV. Moreover, it is also a significant chunk of work in the IDV to 
visualize these data. We will have to get back to this important topic when 
there are sufficient resources to tackle this issue.

> Description of problem: Hi Yuan and Julien, this is grib data from a new data 
> source (ensemble grids from the Navy's FNMOC model) that can be downloaded 
> from ftp://ftp.ncep.noaa.gov/pub/data/nccf/com/gens/prod/fens.YYYYMMDD/HH ...
> I suspect these grib files use grib parameter tables that IDV does not have.  
> Which brings up the question, can a user add customized/new grib parameter 
> tables to IDV?
> The error message appears below.
> Let me know if you need any more info!
