Re: [ferret_users] DODS data reading

[Peter Cornillon <pcornillon@xxxxxxxxxxx>]

Hi Yogesh and Ansley,

Dan Holloway looked at this data set a bit more and he thinks that I  
may have been wrong when I said earlier that there seems to be a server  
problem associated with it. It does fail in the ODC, but he thinks that  
that is because of the number  of variables in the data set, i.e., it  
is a problem in the ODC, not with the server. The error below is likely  
because you forgot the .ascii.

Ansley, is there any way that you can check to see if Ferret can handle  
the dds that the server is returning. It is VERY big and quite  
convoluted, although it appears to be legitimate. Try

http://g0dug03u.ecs.nasa.gov/dods-bin/nph-dods/datapool/MOAA/ 
MYD08_M3.004/2003.05.01/MYD08_M3.A2003121.004.2004136064318.hdf.dds

to look at the dds or

http://g0dug03u.ecs.nasa.gov/dods-bin/nph-dods/datapool/MOAA/ 
MYD08_M3.004/2003.05.01/MYD08_M3.A2003121.004.2004136064318.hdf.das

to look at the das - it's a doosey.
