The Start-of-Season Value (SOSV) provides the value of the Plant Phenology Index (PPI) at the start of the vegetation growing season. The Plant Phenology Index (PPI) is a physically based vegetation index, developed for improving the monitoring of the vegetation growth cycle. The PPI index values, with 5-day satellite revisit cycle, are first used in a function fitting to derive the PPI Seasonal Trajectories, which is a filtered time series with regular 10-day time step. From these Seasonal Trajectories, a suite of 13 Vegetation Phenology and Productivity (VPP) parameters are then computed and provided, for up to two seasons each year. The Start-of-Season Value is one of the 13 parameters. The full list is available in the table 3 of the Product User Manual in the below link section. A complementary quality indicator (QFLAG) provides a confidence level, that is described in table 4 of the same manual. The SOSV dataset is made available as raster files with 10 x 10m and 100 x 100m resolutions, in ETRS89-LAEA projection corresponding to the HRL grid, for those tiles that cover the EEA38 countries and the United Kingdom and for two seasons in each year from 2017 onwards. It is updated in the first quarter of each year.EEA38 (from 2020)United KingdomCopernicusGrowing seasonPhenologyPlantsEnvironmental monitoring facilitiesHabitats and biotopesOrthoimagery <http://www.opengis.net/def/crs/OGC/1.3/CRS84> Polygon((-25 26, -25 72, 45 72, 45 26, -25 26)) Copernicus Land Monitoring Service (requires authentication)https://land.copernicus.eu/en/products/vegetation/high-resolution-start-of-season-value#downloadWEkEO Portal (requires authentication)https://wekeo.copernicus.eu/data?view=cataloguefacets=contactOrg%7EEuropean+Environment+AgencyProduct Information and Technical Documentationhttps://land.copernicus.eu/en/products/vegetationEEA Geospatial Data Cataloguehttps://doi.org/10.2909/a4fdb695-e3b7-4a9d-bba9-47b8a654e484Copernicus Land Monitoring ServiceEnglish
