Context

CS Group responsabilities for Polarization calibration on natural sites are as follows:

• Study

The features are as follows:

• Polarized signal sensitivity analysis :
• Estimation of the diffusion orders contributing to the polarized signal at the TOA
• Influence of the aerosol model
• Influence of surface properties (BRDF, refractive index)
• Influence of sight geometry and AOT
• Parametric analysis Representativeness of BPDF models on desert sites :
• Comparison of measurements and modeling for different BPDF models
• Analysis of the results of inversion of the weighting coefficient of the Maignan model
