I am trying to put together a simple subsetting operation on CORDEX data. It is effectively the simplest data retrieval command followed by ct.cube.select(data, extent=[28., 42., -3., 0.]). The app, however, crashes out with the error "ValueError: dimensions or multi-index levels ['lat', 'lon'] do not exist". As is the case with all most CORDEX files, the data arrays use a rotated pole coordinate system and the corresponding dimensions are called "rlat" and "rlon", so the error is easily enough explained. Does anyone know how to work around this problem?
