Customer: Centre National d’Etudes Spatiales (CNES)

Programme: DTQTIS

Supply Chain: CNES > CS Group SPACE

Context

CS Group responsabilities for Uncertainties of the deserted calibration for the sensors Sentinel3 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 (Code & A.T.B.D.) => Proposal for improvements and corrections
• Development / testing of improvements
• Quantification of the typical uncertainties provided at the input of the code (BRDF, interpolation, radiative transfer, radiometry)
• Application to the 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 of the deserted calibration method. Application to S3.

The processes for carrying out the project are:

• Bibliography, code analysis / improvements, development, validation, actual data application, reports

Technical characteristics

The solution key points are as follows:

• Incommensurate
