Yes, it’s available within update, once I updated the SNAP, the last problem concerning of sen2cor 2.8 already mentioned in this post is solved, Source of the post
When launch the SNAP again similar above problem comes out, and sen2cor 2.8 gives error,
And still doesn’t run for any of the resolutions ALL, 10, 20, 60, once it run finished the process quickly in zero time minutes, and the output result only three bands, couldn’t be opened.
Nevertheless, 2.5.5 works normally with the same product. I run it directly from the SNAP (Tools ---------> manage external tools).
