hello !
i was using the OLCI L2 WFR and i found the reflectance in some places have nagtive value, so i want to change another AC algorithms.the user guides says can change it but i don’t know how or is there another way to get more correct reflectance.
What you obtain are the reflectances already in BAC or AAC, you cannot control the switch, it is done automatically. But you can download the L1 and process with another AC algorithm (C2RCC, Polymer…)
