I am trying to import model data by 


ga-> sdfopen http://nomads.ncep.noaa.gov/dods/gfs/gfs20131219/gfs_00z


e.c.t


using OpenGrads client but I keep getting the following error


Error: nc_open failed to open file "http://nomads....."


NetCDF: I/O failure


gradsdf: Couldn't injest SDF metadata.


 


I can't work out what is going wrong or how to solve this, please help

If you're running 2.0.a8 or later then use Grads. Earlier versions use gradsdap or gradsdods: 


 


http://nomads.ncep.noaa.gov/dods/gfs_hd/gfs_hd20131121/gfs_hd_00z 


Always check the url in a browser before wasting your time as there have been quite a lot of network issues with Nomads in recent months.

Incidently, who knew that the GFS has a 1829m above sea level temp parameter!



 


Incidently does anyone know where the ECM server lives?

However, there's only a very limited set of variables freely available. I'm currently discussing licensing a more complete set for TWO but haven't yet made a decision on whether to go ahead. Not sure whether it's a worthwhile business proposition.


PS: When working on the Nomads you're effectively on a production system. If you're learning then it's much better to download a file and open locally rather than using DODS.
