I tried to apply brdf correction and cirrus correction when I performed the convection from L1C to L2A using sen2cor (version 2.2.1) under Linux.
I suppose I’ve set the proper values in L2A_GIPP.xml file:
<Cirrus_Correction>1</Cirrus_Correction> <!-- 0: no, 1: yes --> <BRDF_Correction>1</BRDF_Correction> <!-- 0: no BRDF correction, 1: , 2: ,11, 12, 22, 21: -->
But the outputs are the same that I had without cirrus correction and brdf correction .
Does that mean that the corrections do not change the outputs at all?
