Anything over 30 ms will choke on the NMC2 feedtype..these are the HIGH
resolution model ouput and are quite voluminous...I believe we will have
success with the "standard" model output. I do not know your data needs,
but if you are only interested in the global model outputs, you can
restrict your HDS feed via regular expressions, to eliminate bandwidth
congestion of used by unwanted data, this will also help insure that you
get all the data from the models you want..

I will place the allow for HDS on our machine:

thelma.ucar.edu


Please let me know if/how this is working for you...we have not fed many
places outside the US and it is always nice to see it work.

Thank you,

-Jeff
