Hello all,

We've been asked a question regarding the largest netCDF file that we are aware of, in terms of a real file containing practical data. I am not aware of any specific single large data file "in the wild", so I thought I would ask the mailing list. Does anybody out there have (or is aware of) a particularly large netCDF file in their collection?

Thanks in advance, have a great evening all,

-Ward
