The Sentinel-2 Multi-Spectral Instrument (S2 MSI) documentation provides an overview of the software and processing framework used for the generation of Sentinel-2 products within the Earth Observation Processing Framework (EOPF). It describes the structure, configuration and behaviour of the Sentinel-2 MSI processing chain, covering the transformation of raw satellite data into higher-level land and surface reflectance products.
The document presents the main architectural principles of the S2 MSI processor and details how product formats, auxiliary data and configuration elements are organised in line with EOPF standards. It explains how the processing chain supports multiple product levels and resolutions, while ensuring consistency, traceability and reproducibility across processing baselines. Overall, the documentation serves as a mission-specific reference that aligns Sentinel-2 MSI processing with the broader EOPF ecosystem, supporting a harmonised and maintainable approach to optical Earth Observation data processing.
