I have a set of NetCDF files that I would like to aggregate into a
single file.

Every file contains a timeseries of values at lat,lon coordinates.  The
timeseries all match across the files and the 2-D areas are adjacent but
not overlapping.

What I would like to have is a single file with a timeseries of values
for the aggregated area.

Browsing through the NCML javadoc I found the Tiled Aggregation type,
and it sounds suggestive of exactly what I want to do, but I haven't
been able to find any usage examples.

If this command does what I want, can somebody provide an example, or a
pointer to one?  If it doesn't, is there another path I can follow to
accomplish my "tiled aggregation"? Perhaps a clever set of parameters to
ncks?

Many thanks,
