Hi Sebastian, Attached, you have a cdl example of NetCDF that can be ploted with the IDV. The NetCDF file must have one time dimension (only one dimension is allowed) and the coordinate variables time, longitude, altitude and latitude (CF Conventions Coordinate Types<http://cf-pcmdi.llnl.gov/documents/cf-conventions/1.5/cf-conventions.html#coordinate-types> ). Your NetCDF have two dimensions, you can delete sps01 and rename data_point to time dimension. You must also add the coordinate variables, and all the variables (coordinate and data) must have the time dimension.
