As I can see processing baseline of images are now 4.0, so they are in new baseline not compatible with 2021 (example: S2A_MSIL2A_20220402T095031_N0400_R079_T33UYU_20220402T130540.SAFE) … how do I download compatible ones?

Use Sentinel Hub API, configured with harmonizeValues option.


Oh ok, but I need original image format, not tifs.


Using Sentinel Hub you can access L2A data directly, as they are. Check this example:

Examples for S2L2A

Use these CURL and Postman examples to access atmospherically corrected Sentinel-2 L2A data with Sentinel Hub API.


You mean to process it from L1C? Or to be able to download ready-to-go one?


this is a sad news, but thank You for the information


Then there is no other option than handling the differences between baseline versions on your side, as there does not exist a repository with new data with old-baseline-values.


btw… did L1C change as well in feb 25th? because using Sen2cor with baseline 3.00 did not fix the problem with different values.
