Land surface phenology from Copernicus Global Land time series

摘要

The phenology in Europe in the period 1999-2016 was characterized by using of time series of different biophysical variables (LAI, FCOVER, FAPAR and NDVI) estimated from the sensors VEGETATION and PROBA-V in the framework of the Copernicus Global Land Service. The Spirits software was used for the smoothing and processing the time series, as well as for estimating the start, length and end of the phenological season. The comparison with ground observations (PEP-725) of the different phenophases of birch and beech showed a RMSE of ～9 days and ～16 days for the timing of the SoS and a RMSE of ～15 days and ～60 days for the timing of the EoS.
