Hello All,

Adding onto Michael's existing thread, I am working closely with him
attempting to figure out the issue we are having with the aggregation of
swath data that has a two-dimensional grid with track and cross-track
coordinates. We have tried using FMRC, joinExisting, and joinNew file
aggregation methods within THREDDS, all with no success.

We tried using many different aggregations methods
that exist within the ncWMS2 interface. We have tried doing the simple
wildcard aggregation attempt by using the wildcard character (e.g.
/ASCAT/nc_L2B_25_daily/2020/*.nc).

We have also tried to use the "Dynamic Services" that is also available
through ncWMS2, but that also did not seem to work with the
multi-dimensional swath data that we are
trying to aggregate.

Finally another method we tried was through geoserver, where we attempted
to use the image mosaic option that it has but that option also proved to
be a dead end.

None of the methods mentioned above worked properly, and we are wondering
if anyone has had any success aggregating swath data with the methods, and
would like to share any
special steps that had to be taken to make said method work. Are there any
other methods I did not mention above that could possibly be able to
aggregate the multi-demensional swath data?

Any insight or help would be appreciated
