[gradsusr] Loading GFS data (DODS) over nomad's ".ascii" option - how to read in grads?

[Stauffer Reto (UNI)]

Dear usergroup

We would like to visualize some GFS products. Actually i get the data 
from the nomad servers "on demand" with

'sdfopen http://nomad3.ncep.noaa.gov:9090/dods/gfs20110927/gfs_master_00z'

THE PROBLEM is that i have so much calls to the server that he kills the 
connection (after ~100 as written on the nomad3 servers page). Now there 
is also an option to load all the data with wget. For example the call is

http://nomad3.ncep.noaa.gov:9090/dods/gfs20110926/gfs_master_00z.ascii?rh2m[14:28][46:46][22:22]

It's the same "file/adress" but with the .ascii? option (selecting one 
variable "rh2m" here for certain timesteps [14:28] and for only one 
gridpoint (lon/lat 46/22). This works fine and i can create the 
ascii-file without any problem

BUT HOW TO READ those files with grads? Can i convert those files? Or 
open directly? Or create a controlfile?

I read all possible hints and pages in the internet but i havnt found 
any solution until now.
Does anyone have some experiences with that approach?

Or is there another option not to run into the "server request restriction"?
