I would like to find a way in Python to aggregate over the slow index (time) of a NetCDF dataset with dimensions (time,y,x) where the files store blocks of time. Apparently NetCDF4-python do this for a NetCDF4 classic file or NetCDF3, but the files are a done deal. Can anyone explain if there is a way to do this in NetCDF4, either with a multfile access or with something like NcML wrappers?
Or does NetCDF4 not do this for a reason that cannot be overcome?
Thanks.
