Customer: Centre National d’Etudes Spatiales (CNES)

Programme: DTQTIS

Supply Chain: CNES > CS Group SPACE

Context

CS Group responsabilities for Uncertainty assessment of the Deserts calibration for SENTINEL3 sensors are as follows:

• Study, Development

The features are as follows:

• Adaptation of an existing tool (R&T CNES) to the SENTINEL3 case
• Analysis of the existing situation (code & A.T.B.D.) => proposal for improvements and corrections
• Development / Testing of improvements
• Quantification of standard uncertainties provided as input to the code (BRDF, interpolation, radiative transfer, radiometry)
• Application to the case of calibration of OLCI and SLSTR sensors
• Extension for use with SENTINEL2 (To be finalized)

Project implementation

The project objectives are as follows:

• Identify and quantify the different sources of uncertainty in the Deserts calibration method. Application to S3.

The processes for carrying out the project are:

• Bibliography, Code analysis/improvements, Development, Validation, Real data application, Reports
