Supply Chain: CNES > CS Group SPACE

Context

CS Group responsabilities for Absolute radiometric calibration - Studies for improving Sade -Muscle tools are as follows:

• Study, development

The features are as follows:

• Improvement hyperspectral interpolation on deserted sites :
• Analysis of available hyperspectres (Gome-2, Onera, Ecostress, Picsand)
• Generation of reference hyperspectres for desert sites
• Application to calibration (MSI, OLCI, SLSTR) Toa spectral integration for deserted calibration :
• Adaptation of muscle/implementation of algorithm
• BOA/TOA integration comparison (Spot-6 and SLSTR calibrations) Rayleigh/glitter calibration :
• Development BRDF Morel & Gentili Correction (Integration Muscle-Neo in progress)
• Study on improving the spectral interpolation of air conditioning reflectances

Project implementation

The project objectives are as follows:

• Improve the modeling of surface reflectance of desert calibration sites
• Replace the spline interpolation made from multi-spectral measures with an interpolation from a hyperspectrans
• Replace the integration of surface reflectance by integration of the simulated signal at the top of the atmosphere

The processes for carrying out the project are:

• Study, tests, regular advancement meetings

Technical characteristics
