The Union aggregation is doing that for you
<netcdf xmlns="http://www.unidata.ucar.edu/namespaces/netcdf/ncml-2.2";>
<aggregation type="union">
<netcdf location="data.nc"/>
<netcdf location="geo.nc"/>
</aggregation>
</netcdf>

Hi,
I'm wondering if the following composition is possible in NcML. I
read tutorial on the web but I could not find a solution yet.
Let's assume that data.nc has no coordinate variables but geo.nc has.
I'd like to create a data.ncml like below to import coordinate
variables from a separate NetCDF file (i.e., geo.nc) so that I can
visualize data variables in data.nc with IDV by opening data.ncml.
<netcdf location="data.nc">
<!-- import geo-location data from external file. -->
<variable name="Latitude" location="geo.nc">
<variable name="Longitude" location="geo.nc">
</netcdf>
Is the above scenario possible with NcML via netcdf-java?
If so, what NcML tag & attribute should I use to import variables from
external files?
Regards,
