MERIS/(A)ATSR Glint Correction

Hi, I need to apply MERIS/(A)ATSR Glint Correction to some images. This correction was implemented in BEAM however I can not find it in SNAP.
Someone knows where I can find it?
Thanks in advance

This is one of the operators which is not yet migrated to SNAP.
For now you have to use BEAM for the Glint Correction. The results can be used in SNAP.
There are plans to migrate these heritage operators but the priority is not very high.
Actually when and which operators will be migrated depends on user demand. So the priority increased with your enquiry.
