Many filters are used to reject heterogenous cloud fields and broken fields clouds in the AERO-AC products. However, 3D radiative cloud effects still have some impact on the retrieval accuracy. For the polarization, these effects were evaluated in section 2.2.3b of Waquet et al., (2013) and in section 5 of Peers et al., (2015) for the part of the algorithm that uses intensity measurements. The algorithm was also applied to broken fields clouds and bumpy clouds in Cornet et al., (2018). In case of heterogeneous clouds, various errors on the retrieved aerosol optical thickness (from small to large > 40%) may occur depending on the viewing geometry sampled by the sensor and cloud cover type.
