True Color OLCI Sentinel-3A

The Sentinels are a suite of satellite missions developed to serve the operational needs of the European Copernicus program for Earth observations. NOAA CoastWatch/OceanWatch provides Sentinel data to US users through official arrangements with ESAEUMETSAT and the European Commission.

Synthetic Aperture Radar Imagery (NRCS)



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.


MSI Sentinel-2 Imagery

MSI Sentinel-2 high spatial resolution imagery and data from Copernicus are served from CoastWatch for coastal US regions in near real time as the data become available.  JPEG and TIF images as well as zipped Level 1C data are available.
