The Sentinel-1 Level-1 / Level-2 Reprocessing (S1 L12 RP) documentation provides a comprehensive overview of the data reprocessing framework for Sentinel-1 products within the Copernicus programme and the Earth Observation Processing Framework (EOPF). It describes the objectives, scope and structure of the reprocessing activities that support the generation of consistent and up-to-date Level-1, Level-2 and Analysis Ready Data (ARD) products.
The document brings together information on processing baselines, auxiliary data files, product formats and intermediate datasets required for Sentinel-1 reprocessing, with particular attention to alignment with EOPF conventions and Python-based processing architectures. It explains how legacy processing elements are adapted and harmonised to ensure reproducibility, traceability and long-term maintainability of the products. Overall, the documentation serves as a mission-specific reference that connects Sentinel-1 reprocessing activities to the broader EOPF ecosystem, supporting a standardised and future-proof approach to Earth Observation data processing.
