Seasonal Trajectories, 10-daily

Short description

Seasonal Trajectories (ST) product is a filtered time series of Plant Phenology Index(PPI) provided yearly on a 10-daily basis at 10m resolution . It is part of the Copernicus Land Monitoring Service (CLMS), pan-European High Resolution Vegetation Phenology and Productivity (HR-VPP) product suite. The Seasonal Trajectories PPI is derived through fitting a smoothing and gap filling function to the yearly time-series raw PPI values generated from Sentinel-2 satellite observations. In addition to the PPI band, a QFLAG band indicating the quality of the smoothing process is included. The Seasonal Trajectories provide the vegetation status for each pixel on a regular 10-day time step from January 1 2017 onwards over the EEA39 region. More information about ST product is outlined in the product user manual
