Programme: DTQTIS

Supply Chain: CNES > CS Group SPACE

Context

CS Group responsabilities for BPDF models and applicability to high spatial resolution are as follows:

• Bibliographic research, synthesis, simulations

The features are as follows:

• Identification of BPDF models in the scientific literature (natural or artificial surfaces).
• Application of the Maignan code to evaluate the Nadal, Bréon, Maignan and Litvinov models on POLDER data.
• Simulation of the polarized field at TOA with the SOS radiative transfer code.
• Analysis of the angular and spectral variation of the degree of polarization (DOP) on the surface and at the TOA.

Project implementation

The project objectives are as follows:

• Bibliographic review of bidirectional polarization models (BPDF) adaptable to high spatial resolution sensors.
• Test of application of these models to discretize the types of surfaces observable from space.

The processes for carrying out the project are:

• Bibliography, study, simulations, regular meetings
