Context

CS Group responsabilities for Absolute radiometric calibration - Studies for improving SADE-MUSCLE tools are as follows:

• Study, development

The features are as follows:

• Improved hyperspectral interpolation on desert sites :
• Analysis of available hyperspectra (GOME-2, ONERA, ECOSTRESS, PICSAND)
• Generation of reference hyperspectra of desert sites
• Application to calibration (MSI, OLCI, SLSTR) TOA spectral integration for desert calibration :
• Adaptation of MUSCLE tools/Implementation of the algorithm
• BOA/TOA integration comparison (SPOT-6 and SLSTR calibrations) Rayleigh/Glitter calibration :
• Morel&Gentili BRDF correction development (MUSCLE-NEO integration in progress)
• Study on improving the spectral interpolation of reflectances CLIMZOO

Project implementation

The project objectives are as follows:

• Improving surface reflectance modeling of desert calibration sites
• Replace Spline interpolation made from multi-spectral measurements by interpolation from a hyperspectrum
• Replace the integration of the surface reflectance with the integration of the simulated signal at the top of the atmosphere

The processes for carrying out the project are:

• Study, tests, regular progress meetings
