Hi Ari,

I'm sorry you are having trouble downloading the data you need.  However, I'm 
not familiar with a server at tds.ucar.edu - it's not one of ours (Unidata, 
that is).  Did you mean thredds.ucar.edu?  That would make more sense, and is a 
Unidata maintained TDS.  However, the Thredds Data Servers maintained by 
Unidata do not require login credentials, though it is quite possible that 
other organizations do.  If you know the hosting organization and have contact 
information for them, you'll need to contact them directly to find out what 
happened to their server.

Regards,
