How can I calibrate Sentinel-2 products, to extract the reflectance?
I've downloaded few Sentinel-2 products from https://scihub.copernicus.eu/s2/#/home, and opened them with SNAP but its radiometric calibration is dedicated only to SAR products.
On ENVI, the Radiometric calibration tool is seemingly only capable of extracting the radiance. What is the difference between the radiance and the reflectance? Is the estimation of the radiance counted as a radiometric calibration of a product?
