This is my first time trying to use DOS1 method in Sentinel-2 I have four images to mosaic in L1C and need them to be L2A. I have tried:
- Atmospheric correction in QGIS at the L1C files I downloaded and then merge them, but have wrong colours in the RGB like so: (Image 1)
- After I have the mosaic (and clipped the area of interest) I use the DOS1 method, but the output is too bright: (image 2)
My results are completely different (all of them with pixel values [0,1]).
What is the correct way to do atmospheric correction in Sentinel-2 from L1C to L2A?
