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.

Hi Flowers

You can run L2gen at your image, you will got Rrs.
