+## About
+[Official documentation](https://land.copernicus.eu/en/products/snow/fractional-snow-cover)
+
+The Cloud Classification (CC) product provides information on the extent of clouds and cloud shadows derived from optical satellite data acquired by the Sentinel-2 constellation. It is generated in near real-time at European scale, with a pixel spacing of 20 m x 20 m. Cloud detection is performed at a 120m spatial resolution. It is available for the period from 2016 to the present and used to produce the CLMS High-Resolution Water, Snow and Ice datasets (HR-WSI), which rely on Sentinel-2 imagery. More information in the products documentation here.

+## About
+[Official documentation](https://land.copernicus.eu/en/products/snow/high-resolution-gap-filled-fractional-snow-cover)
+
+The daily cumulative Gap-filled Fractional Snow Cover (GFSC) product provides pixel-wise snow cover extent as a percentage (0% – 100%) with a spatial resolution of 60 m x 60 m. It is generated on a daily basis at European scale based on synthetic aperture radar (SAR) data from the Sentinel-1 constellation and optical imagery from the Sentinel-2 constellation. The product is generated by merging all available Sentinel-1 and Sentinel-2 observations acquired over the previous seven days to produce a spatially complete composite of snow conditions, thereby reducing data gaps caused by cloud cover and sensor coverage limitations. Snow information derived from Sentinel-1 is focused on the detection of wet snow in high-mountain areas. It is available for the period from 2016 to the present. More information here.

+
+The Sentinel-1 & Sentinel-2 Snow Phenology (SP S1+S2) product characterizes the timing and duration of the snow season. For each pixel and for a given hydrological year, it provides the number of days with snow cover, as well as the first and last day of the longest continuous snow period. The hydrological year starts on 1 September. The product is generated at the European scale with a spatial resolution of 60 m × 60 m, consistent with the input snow cover maps derived from optical satellite data acquired by the Sentinel-2 constellation and from C-band Synthetic Aperture Radar satellite data acquired by the Sentinel-1 constellation (Gap-filled Fractional Snow Cover - GFSC). It is available for the period from 2016 to the present and can be downloaded in multiple projections and pixel spacings. More information here.
