Use Sentinel Hub API, configured with harmonizeValues option.

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

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.

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

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.

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

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