Hi Paddy, Ah! Looking again on your schema I see that you have deleted the imageIndex attribute: I think that this is the problem.
Let me explain: A NetCDF can be seen as a multidimensional dataset (a kind of a hypercube). >From an ImageIO <https://docs.oracle.com/javase/7/docs/api/javax/imageio/package-summary.html>point of view (the low level Oracle API for raster I/O) read <https://docs.oracle.com/javase/7/docs/api/javax/imageio/ImageReader.html#read(int,%20javax.imageio.ImageReadParam)> operations are performed on top of an ImageReader <https://docs.oracle.com/javase/7/docs/api/javax/imageio/ImageReader.html> (which has been set on an input, such as a file or a stream), by specifying a set of reading params <https://docs.oracle.com/javase/7/docs/api/javax/imageio/ImageReadParam.html>(such as subsampling, and region to be read) and an imageIndex, indicating which underlying image need to be read. Therefore, a Multidim dataset can be seen as a set of 2D images where the number of images is the product of: number of time values * number of elevation values * number of other dimensions, for each available variable. Your schema doesn't contain the imageIndex so there is no way to associate a specific time + a specific elevation pair to a specific 2D slice of the NetCDF dataset. Here below, an extract (with pgadmin) of one of the tables for the polyphemus dataset configured by my previous test: (See the blue marked record) So that when the query asks for a record with time = 2013-03-01 00:00:00, elevation = 450 and fileDate = 2013-03-01 the result contains imageIndex = 679. The GeoTools reader will then specify imageIndex = 679 to the underlying NetCDF ImageReader which will access to the section referring the specified elevation and time subset. You should retry by making sure to add the imageIndex attribute to the schema (you can check the default schema in the example <http://geoserver.geo-solutions.it/multidim/en/imagemosaic/mosaic_indexer.html#imagemosaic-xml-indexer-example> of the polyphemus dataset from multidim training) and reconfiguring your data (Make sure to restart from a clean situation to avoid partially configured mosaics). Please. Let me know if that fixes your problem.
