[ncl-talk] How to process numerous files(data) in NCL

[Rashed Mahmood]

Hi Huang,
This question is a bit vague, at least I am not what statistics you are
trying to calculate. NCL can do array processing for certain things,
however, for a better answer to your specific needs, you would need to be
specific about what exactly you are trying to do?
