Customer: Centre National d’Etudes Spatiales (CNES)

Programme: DTQTIS

Supply Chain: CNES > CS Group SPACE

Context

CS Group responsabilities for Calibration study of the PRISMA hyperspectral sensor are as follows:

• Study, development

The features are as follows:

• Comparison of interpolation methods (cubic spline vs hyperspectral method)
• Analysis of the influence of the reference sensor (Sentinel-2 vs Sentinel-3) on the calibration results
• Analysis of the influence of AOT (default value, MODIS, CAMS)
• Analysis of the influence of aerosol models
• Comparison with MUSCLE (multispectral, cubic spline)
• Analysis of the different campaigns

Project implementation

The project objectives are as follows:

• Adapt the inter-calibration method on desert sites, applicable to multispectral sensors, to a hyperspectral sensor
• Test the tool on PRISMA data

The processes for carrying out the project are:

• Study, tests, regular progress points
