Danny, it looks like the NetCDF libraries are guessing that your station variable is a dimension because its name matches its dimension name, but it is not a standard axis and not a supported type. If this was the only problem, you could rename the variable.
The larger problem is that this file appears to be a collection of point data. As far as I know, NetCDF support is limited to coverages, that is, files that define a variable over a two-dimensional spatial grid (and higher dimensions). Your file does not have a supported spatial structure because it represents a collection of points. Can you extract the samples and store them in a database, or convert them to another file format such as shapefiles or a property file that supports point data? Kind regards, Ben.
