Upper air RAOB data can be displayed as soundings. You can access RAOB data as soundings either from remote ADDE servers (using the Point Observations->Soundings->Remote chooser, pictured below) or from local files (using the Point Observations->Soundings->Local chooser). The only difference between these two choosers is specifying the source of data. You either select an ADDE server and press Connect, or you can select a file containing RAOB data. For more information on how to use these choosers, see Getting Started - Displaying RAOB Sounding Data.
