 The daily composite of Synthetic Aperture Radar (SAR) Normalized Radar Cross Section (NRCS) imagery covering the Arctic and sub-Arctic maritime regions over a period of one day are available at 1-km resolution. These high-resolution, weather- and time-agnostic measurements of surface backscatter contain detailed information tailored for sea ice classification purposes.

 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.
