Customer: Centre National d’Etudes Spatiales (CNES)

Programme: TRISHNA

Supply Chain: CNES > CS Group SPACE

Context

CS Group responsabilities for Calibration methods on terrestrial targets in thermal infrared - Applicability to TRISHNA are as follows:

• Bibliographic research, synthesis

The features are as follows:

• Identification of IRT sensor calibration methods and applicability analysis to TRISHNA :
• TIRS / Landsat-8 (marine targets with buoys, instrumented terrestrial sites, inter-calibration),
• ECOSTRESS, ASTER/TIR (instrumented terrestrial sites),
• MODIS Airborne Simulator (field measurement campaigns). Identification of data networks used for absolute calibration in VIS-SWIR and IRT. Identification of inter-sensor calibration methods (SNO, SIC, DDM methods). Identification of the impact of BRDF in IRT and correction procedures.

Project implementation

The project objectives are as follows:

• Bibliographic review of absolute calibration methods on terrestrial targets in the IRT with a view to applicability to TRISHNA
• Bibliographic review of the different BRDF models in IRT (with a view to correcting the directional effects of the surface)

The processes for carrying out the project are:

• Bibliography, study, regular meetings
