The atmospheric correction of Sentinel-2 is rather complex and hard to implement yourself. Here at mundialis we use "sen2cor": http://step.esa.int/main/third-party-plugins-2/sen2cor/ An alternative may be SMAC, see for example http://www.cesbio.ups-tlse.fr/multitemp/?p=6013 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.
