@Michael,
You can try the TiledAggregation.
An example it's shown on this mail thread:
https://www.unidata.ucar.edu/mailing_lists/archives/thredds/2016/msg00251.html
And in Unidata's GitHub
https://github.com/Unidata/thredds/issues/778

P.S: The tiled ggregation reference can be found at
https://docs.unidata.ucar.edu/netcdf-java/5.1/userguide/annotated_ncml_schema.html

Greetings Michael!
I don't know of any examples of swath datasets being aggregated using
NcML (perhaps others do?). I think the basic mechanics of aggregating
would work, but the higher level services, like the NetcdfSubset
service, WCS, or ncWMS, would not work. The sticking point with those
services would be the time varying spatial coordinates - that's
something that is not supported at this time.
Cheers,
Sean

Are there any THREDDS catalog aggregation examples for swath data that
has a two-dimensional grid with track and cross-track coordinates? Any
ncml examples of this working in anyone's production THREDDS catalog?
We have tried the "joinExisting" methods we use for grid datasets with
a "time" component, but this same approach does not work on
multi-dimension swath data.
We have several satellite/swath datasets that we would like to
virtually aggregate and present via WMS to web mapping platforms via a
single THREDDS URL but have thus far been unsuccessful.
for example, here is the full listing of all the swath files we would
like to virtually aggregate,
