A Harmonized Surface Reflectance Product

Sentinel-2 and Landsat products represent the most widely accessible medium-to-high spatial resolution multispectral satellite data. Following the recent launch of the first out of two Sentinel-2 satellites, the potential for synergistic use of the two sources creates unprecedented opportunities for timely and accurate observation of Earth status and dynamics. Thus, harmonization of the distributed data products is of paramount importance for the scientific community. Activities to harmonize data products are on their way, yet more coordination is needed to allow the majority of users to easily and effectively include both data types into their work.
