Chris, Yes, ragged arrays are supported in netcdf-4 by the VLEN type. I have never used this type, so I can only point you to additional documentation that might help. http://www.unidata.ucar.edu/software/netcdf/docs_rc/data_type.html#vlen_types http://www.unidata.ucar.edu/software/netcdf/docs/dvlen_8c.html The first reference refers to "Variable Length Arrays in The NetCDF C Interface Guide", but I have not found this exact documentation. I recall seeing a few VLEN sample programs in the test suite in some recent netcdf-C source code distribution. These would be genuine working examples that you could learn from.
