BRDF correction l2gen

[aewindle]

I'm processing S3 OLCI data from level 1 to level 2 using l2gen. I'm wondering if L2 outputs are corrected for BRDF effects? Is there a way to change this parameter?

Thanks,
Anna

Anna,
Yes to both. The input option brdf_opt controls this:

Code: Select all

   brdf_opt (int) (default=-1) = Bidirectional reflectance correction
        0: no correction
        1: Fresnel reflection/refraction correction for sensor path
        3: Fresnel reflection/refraction correction for sensor + solar path
        7: Morel f/Q + Fresnel solar + Fresnel sensor
       15: Gordon DT + Morel f/Q + Fresnel solar + Fresnel sensor
       19: Morel Q + Fresnel solar + Fresnel sensor

The default setting is brdf_opt=7

Regards,
Sean
