The origin of the “Tile artefacts” you are reporting is,
that the processing baseline of Sen2Cor is procesing L1C products tile
by tile, with each tile processed independent from the others. Each tile
is different and gives different aerosol optical thickness. This
results in differences in the final BOA-product.
Is it possible to make the tile-by-tile processing optional? These artificial edges in the images are quite annoying, and if all it takes to process an entire image in one go is a few extra GB of RAM, I for one would like to switch from tile-based to entire-image-based processing. As it is, roughly half the images we have processed by now have received these edges – some harsher, some less so, but it’s making some of them unusable. If a processing run takes hours and we then sometimes need to discard the result, it’s tempting to simply make do with the original images and not even attempt the atmospheric correction…
