• Data Download: via OpenDAP or ftp://ftp.cls.fr/pub/oceano/AVISO/SSH/duacs/global/nrt/madt/merged/uv/
  
• Data Conversion:  These instructions assume local access to ESRI's ArcGIS software - access to ArcGIS via remote desktop is also available.  These instruction require the Marine Geospatial Ecology Tools (MGET) for ArcGIS. 

                 In ArcGIS toolbox, under Marine Geospatial Ecology Tools -> Data Products -> Geostrophic Currents -> AVISO -> Download from OPeNDAP server -> Download Aviso Geostrophic Currents Dataset to ArcGIS Rasters

                U and V components are output as separate datasets.
