The atmospheric correction of Sentinel-2 is rather complex and hard to
implement yourself.
Here at mundialis we use "sen2cor":

An alternative may be SMAC, see for example

In your case, consider to download the SNAP toolbox from ESA, and
sen2cor as a plugin to it.

The corrected Sentinel-2 bands can then be imported into GRASS GIS
using "r.import" or the graphical user interface.
