=> Here are the zones where Sentinel-2 data are processed to L2A by THEIA. The data are available here.. The red tiles are already available and processed in NRT. The other zones will be added progressively.
These little squares were selected through the Theia Sentinel-2 call for proposals. CNES Muscate center processes these tiles to Level 2A using MAJA processor, . L2A images provide ortho-rectified images which are corrected from atmospheric effects and provided with a cloud and cloud shadow mask.
