Within this contribution, the procedures for ensuring the data quality within the ground segments of the hyperspectral DESIS and EnMAP missions are presented.
In addition to the approaches for on-board calibration and instrument monitoring, the operational data quality control is included within the L0, L1B, L1C and L2A processors.
Focus is set on the quality of the generated data products, including selected aspects of the radiometric and spectral scene properties, ortho-rectifcation and the atmospheric correction. Also selected aspects of an uncertainty estimation related to the radiometric and spectral properties and the L2A product are presented.
Finally, the potential of the DESIS mission on board the ISS MUSES platform for improved site characterization and sensor cross-calibration (esp. with HISUI) is highlighted.
