isardSAT will carry out a number of validation activities, which will address the following main areas:

1. Instrumental calibration and validation activities (for altimeter):
• Instrumental CAlibration Research for Understanding Sentinel-6 performance (ICARUS)
• Calibration and Validation of the S6 altimeter Sigma-0 and the radiometer brightness temperature over natural surfaces
• Sentinel-6 Altimeter Calibration using Point Targets (CaPoTa) – includes IEEC

2. Altimeter Level 1 and Level 2 product validation and calibration:
• for altimeter: Sentinel-6 Altimeter Calibration using Point Targets (CaPoTa)
• for radiometer: Calibration and Validation of the S6 altimeter Sigma-0 and the radiometer brightness temperature over natural surfaces

3. Detailed investigation and evolution of altimetric Level 1 and Level 2 processing algorithms:
- DDP and FF:
• Sentinel-6 Altimeter Calibration using Point Targets (CaPoTa)
• Validating Algorithms Levels 1A and 2 in Ebre RIver Area (VALERIA)
- Geophysical retrievals algorithms:
• for Ocean: Amplitude Compensation and Dilation Compensation Algorithm (ACDC) Validation for S6 (ACDC6)
• for Coast: COastal Range ALtimetry for Sentinel-6 (CORALS)
• for Hydrology: Validating Algorithms Levels 1A and 2 in Ebre RIver Area (VALERIA)
• For Radiometer: Calibration and Validation of the S6 altimeter Sigma-0 and the radiometer brightness temperature over natural surfaces

The proposed activities, including their objectives and proposed plan, will be presented.
