Re: 20050711:IDD Model Feeds via Unidata

Hi Shuyi,

Yes, I have been told (have not investigated myself) that the grids
available via ftp differ from the grids we deliver via the IDD..I have
been told that the ftp site has more grids...

Yes, it sure is easier to work it through the ldm..:)

I will check, and make available a list of the differences.

I look forward to hearing back from John and working through this issue.


Cheers,

Jeff
