[gradsusr] dods server for CMIP5 data?

[Haibin Li]

Hello Jennifer,

Thanks for your exhaustive explanation. I had a bit hard time yesterday 
to use the web interface and wget to download the data. The search did 
not perform well if using chrome, I always ended up with "garbage" files 
that I do not need.
When I use IE, everything worked just fine. The other inconvenience I 
came across is that it is not possible to do multiple variables 
searching simultaneously (well, Probably just I did not how to do it).

Regards,
Haibin
