The following map displays the ocean surface winds at a 10m height derived from WindSat microwave brightness temperatures. WindSat, the first space borne polarimetric microwave radiometer, was developed by the Naval Research Laboratory under sponsorship of the U.S. Navy and NPOESS. For additional information on WindSat, please visit IPO WindSat web site. The ocean vector wind retrievals shown here were retrieved from polarimetric brightness temperature measurements (Stokes parameters) using the WindSat-1 model function, which was developed by the Ocean Surface Winds Team at the NESDIS Office of Research and Applications. The data set currently available covers the period from September 2003 through February 2004. The map below has been divided into 30x20 degree bins for closer examination between latitudes of 80N to 80S and longitudes of 180W to 180E. Click on the desired geographical location to zoom in on a particular 30x20 degree bin. Any comments or suggestions are welcome.

Please Note: These wind data are derived from a preliminary wind vector retrieval algorithm, developed at NOAA/NESDIS, that has not yet been fully validated. The current "rainflag" does not flag all rain contaminated retrievals; more comprehensive rainflags are being pursued. Also, this web site is not maintained with 24x7 support.
