Sentinel-3 l2gen


Hi - I am trying to generate remote sensing reflectance from L1 Sentinel-3 data. How would I go about doing this through SNAP?


In the menu you can find the Radiance-To-Reflectance processor. At Optical / Preprocessing.


Does it come down in the correct units?


Actually it computes TOA Reflectances and not Rrs.
It just uses the following equation:

Probably you want to divide the results by Pi to get Rrs values. For this you can use Band Maths.
