The Vegetation Status Indicators product consists of several maps informing about the evolution of the green vegetation corresponding to the crop vegetative development.
A set of 3 indicators is produced:
- The NDVI, the most popular indicator operationally used for vegetation monitoring, provided to ensure continuity with existing long term time series, thus allowing anomalies detection;
- The LAI, an intrinsic canopy primary variable that should not depend on observation conditions, which determines the size of leaf interface for exchange of energy (including radiation) and mass between the canopy and the atmosphere. FAPAR and FCOVER biophysical variables are already available on-demand in the Sen2-Agri system. They will be by-default delivered in the L3B product starting from the version 1.9;
- Phenology indices, also referred to as NDVI metrics, which inform about specific key parameters of the growing season (starting date, length and date of the maximum growth rate).
More information is available in the corresponding product descriptive datasheet.
