Hi,
I would like to know if L2A products need atmospheric and radiometric corrections. If they do, can I use Snap for it ?

L2A products are already atmospherically corrected, what you see are bottom surface reflectance.
Thank you @abruescas
what about the radiometric correction, is it required?
No, radiometric correction is also included.
Thank you for your response
What algorithm is used for radiometric correction? Is a specific DEM used? How can one re-create that using sen2cor as a user?
this is discussed and answered here:
