Nomads NCP Dods - What ist the Standard-Grid?

[UwBeInt]

Hi

I use GrADS with a Direct-Data linked to the NCEP/Nomads Dods Data Server and use gfsp0.25tile.

My Question is, what is the Default Grid from this Source?
I have created the namelist.wps on my own Server for 2 Domains with Gridpoints at 3km.

Do i have a Option to get also the 3km Grid from Dods or i only can use the standard-grids?
What ist the standard.. 12km? 24km? 5km? Can you tell me please?

Thank you very much.

Best Regards from Switzerland
