|Spaceborne Synthetic Aperture Radar (SAR) imagery maps the surface microwave radar reflectivity at resolutions from a sub-meter to 100 m depending on the particular SAR satellite and mode. Since a radar provides its own illumination, imagery is independent of the time of day. At typical radar frequencies, SARs can image through clouds, so SARs are considered "all-weather" instruments. Several gephysical parameters can be derived from SAR including sea surface wind speed.|

|Ocean Surface Vector Winds (OSVW; magniture and direction) from the Advanced Scatterometer (ASCAT) on Metop-A and Metop-B.|
|The ABI SST data are produced from GOES-16 satellite using the NOAA Advanced Clear-Sky Processor for Ocean (ACSPO) v2.50 enterprise system. Currently, only near-real time (NRT) data are produced at STAR, with a ~2days latency. The data are available in NetCDF4 format, compliant with the GHRSST Data Specifications v2 (GDS2). Currently, the data are not archived and only available at this Coast Watch page as a 2week rotated buffer. There is a plan to reprocess the ABI data, for the full GOES-16 mission.|
