Ocean Surface Currents Analyses Realtime (OSCAR) data access system provides global data of operational ocean surface velocity fields to a broad-based user community via a web-based interactive data selection interface. The OSCAR data is automatically computed from gridded fields of surface topography and wind derived from satellite altimeter and vector wind data through methods developed at Earth & Space Research (ESR), The web-based interactive data access system has an automated procedure to retrieve the dataset that is stored on data servers at ESR and NOAA/NESDIS, and it makes it easy for user to make various data listing, plotting and downloading of these datasets. Some key features included in the Web access system are: (1) automated data update procedure; (2) direct access to global data (70S 70N in latitude and entire longitude) from Oct. 1992 to present; (3) data display of vectors and/or speed over lat-lon map, lat-time section, time-lon section, and time series; (4) data download for selected regions and time range; (5) two selectable filtered/unfiltered modes available with data type of 5-day interval, monthly mean, long term mean, and seasonal mean; (6) interactive web interface selections of location range, time range, and other plot/downloading options; (7) data available through OPeNDAP/DODS. The OSCAR data website has been used extensively by scientists and researchers for research purpose, and it is also used by others, such as fisherman and school students, for informational purpose. The OSCAR Web site is available at http://www.oscar.noaa.gov.
