Composite: merging image time series to build a suitable synthetic product

The Cloud-free Reflectance Composite product provides a cloud-free temporal synthesis of surface reflectance values in the 10 Sentinel-2 bands designed for land observation.

It is delivered with several masks that will help appraising its quality.

The compositing period can be selected between 30 and 50 days for a given site. This provides flexibility with regard to local cloud coverage conditions and enables the production of a high quality information.

The product is delivered on a monthly basis to ensure a proper monitoring of the observed areas and includes relevant additional information to support future use and interpretation.

More information is available in the corresponding product descriptive datasheet.
