Dear Brian,
You could consider using an ImageMosaic coverageStore of NetCDF file(s).
At the moment it's the only format implementing the *harvest* method (which
is invoked when you send a REST update request similarly to what you did).
Harvest allows to add new granules to the collection or update existing
ones.
Moreover, when the underlying NetCDF Reader (involved by ImageMosaic)
notices that a file has been updated, it also does a reset of its internal
index.
If my memory serves me right, some users already used this approach for
time-growing NetCDFs.
That being said (in order to answer your questions):
1) you can take a look here:
http://docs.geoserver.org/latest/en/user/rest/examples/curl.html#uploading-and-modifying-a-image-mosaic
the XPOST commands
2) yes, using imageMosaic. From a "pure NetCDF coverageStore" point of
view, the harvest method isn't implemented yet so the NetCDF reader should
be reinit (GeoServer cache cleanup is probably needed).
3) coverageStore is the right one.
Hope this helps.
Cheers,
Daniele
