Output of the optical retrievals of snow and ice properties using Sentinel-3 OLCI instrument::
- mosaics of top-of-the-atmosphere OLCI reflectances
- spectral/broadband albedo
- Snow specific surface area (SSA) and optical grain diameter
- cloud mask

The current ver. 1 daily product has 1 km horizontal resolution.

The featured regions provide coverage for Arctic glaciated land ice areas (ranked by area): Greenland; Northern Arctic Canada; Southern Arctic Canada; Svalbard; Novaya Zemlya; Severnaya Zemlya; Iceland and Frans Josef Land
