 Currently, both the NOAA SPC and SHARP server datasets are able to offer world-wide observed soundings.  While the SPC server is handled by the meteorologists at the Storm Prediction Center, the SHARPpy development team has been granted server space at the `University of Oklahoma <http://meteorology.ou.edu>`_ to generate various datastreams (e.g. international soundings).  Data from the SHARP server is generated by GEMPAK binaries that merge realtime standard and significant level data accessible `here <http://weather.rap.ucar.edu/upper/Current.rawins>`_.  Archived soundings were downloaded from the publically available `GEMPAK data archive <http://mtarchive.geol.iastate.edu>`_ managed by the `Iowa Environmental Mesonet <https://mesonet.agron.iastate.edu>`_.  Data from this archive starts on January 1st, 1946.  Decoding of this dataset (and the real-time international data stream on SHARP) are performed by the GEMPAK ``snlist`` binary distributed in the `NWS SOO's BUFRgruven package <http://strc.comet.ucar.edu/software/bgruven/>`_.
