A Harmonized Surface Reflectance Product
Landsat and Sentinel-2 data represent the most widely accessible moderate-to-high spatial resolution multispectral satellite measurement. Following the launch of the two Sentinel-2 satellites in 2015 and 2017, the potential for synergistic use of Landsat and Sentinel-2 data creates unprecedented opportunities for timely and accurate observation of Earth status and dynamics. Harmonization of the Landsat and Sentinel-2 data is of paramount importance for the scientific community. This research project prototypes the harmonization for the entire North America and other globally distributed test sites. Technical details of harmonization can be found in the following paper and the User Guide in the Documents section.
