Copernicus High Resolution Water Snow and Ice Monitoring: Cloud Classification (CC) 20m (2025-now)

The Cloud Classification (CC) product is generated in Near Real-Time at European scale based on optical satellite data from the Sentinel-2 constellation. The product provides the extent of clouds and cloud shadows with a pixel spacing of 20 m x 20 m.
CC is one of the products of the pan-European High-Resolution Water Snow & Ice portfolio (HR-WSI), which are provided at high spatial resolution from the Sentinel-2 and Sentinel-1 constellations data from September 1, 2016 onwards.
The CC product is distributed in raster files covering an area of 110 km by 110 km with a pixel size of 20 m by 20 m in UTM/WGS84 projection, which corresponds to the Sentinel-2 input L1C product tile. Each product is composed of separate files corresponding to the different layers of the product, and another metadata file.
