Hi List,
Thanks John for your feedbacks on gribCollections.
I question I have on this topic is:
once configuring a NetCDF Dataset on top of a ncx3 file built on top of a
GribCollection, is it possible to somehow "query" the index to know which
underlying gribs are involved by a specific range? (As an instance: which
files have data for to time=T0?)
Cheers,
Daniele
