TL;DR: Sentinel-3 as mentioned in this paper is an Earth observation satellite mission specifically designed for Global Monitoring for Environment and Security (GMES) to ensure the long-term collection and operational delivery of high-quality measurements to GMES ocean, land, and atmospheric services, while contributing to the emergency and security services.

TL;DR: The Radiometric Calibration Network (RadCalNet) is an effort to provide automated surface and atmosphere in situ data as part of a network including multiple sites for the purpose of optical imager radiometric calibration in the visible to shortwave infrared spectral range.

TL;DR: CARD4L aims to enable non-expert users access to products that have been processed ‘far enough’ to be suitable for immediate analysis for a range of applications, while ensuring they are not too specific to only be used for particular topics or areas.

TL;DR: The successful completion of the commissioning phase has led to the sensors being declared fit for operations and the radiometric calibration of the AVNIR-2 sensor is stable and agrees with the Landsat-7 Enhanced Thematic Mapper Plus and the Envisat MEdium-Resolution Imaging Spectrometer calibration.

TL;DR: The overarching goal is to enhance user confidence in satellite-based data and characterise inter-s sensor inconsistencies, starting from at-sensor radiances and paving the way to achieving the interoperability of current and future land-imaging systems.
