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.
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:
