Abstract

In the framework of this paper, we aim at characterizing cloud heterogeneity effects on radiances, namely: The errors due to unresolved variability (the so-called plane parallel homogeneous (PPH) bias) and the errors due to the neglect of transversal photon displacements (independent pixel approximation (IPA) bias). 3D radiative transfer simulations of nadir reflected radiances in the presence of realistic inhomogeneous cloud fields sampled at different spatial resolutions are going to be performed and compared to their 1D counterparts. Results will be linked to the spatial resolution of different virtual sensors. Further, synergetic use of cloud properties defined at different spatial resolutions are going to be investigated.
