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

The features are as follows:
- Polarized signal sensitivity analysis :
- Estimation of dissemination orders contributing to the polarized signal to the TOA
- Influence of the aerosol model
- Influence of surface properties (BRDF, refraction index)
- Influence of aiming and AOT geometry
- Parametric analysis
Representativeness of BPDF models on desert sites :
- Comparison of measurements and models for different BPDF models
- Analysis of the Inversion results of the Maignan model weighting coefficient
Project implementation
