Greetings,
I have been attempting to create an image mosaic for NETCDF files like this one (http://54.183.9.182/wff_153080300.nc) that I want to index by the time dimension in order to add additional forecast files as they become available. I am using the 2.9 SNAPSHOT version from 11/17 for all components. I have tried to simply specify the directory within which this file sits as an image mosaic store, but this results in the following error : 19 Nov 01:01:54 WARN [netcdf.NetCDFGeoreferenceManager] - Unsupported axis: double lat(y=299, x=399);

I am however able to make a simple NETCDF store of the mentioned file, and expose layers from it. Any advice on how to proceed with successfully setting up an image mosaic for these NETCDF files would be greatly appreciated. Steve Ferguson
