The Fraction of green Vegetation Cover (FCOVER) corresponds to the fraction of ground covered by green vegetation. Practically, it quantifies the spatial extent of the vegetation. It is independent from the illumination direction and it is sensitive to the vegetation amount. FCOVER is derived from the Leaf Area Index (LAI) and a number of structural parameters of the canopy. Used are top-of-canopy directionally normalized reflectances from SPOT-4 and -5 VEGETATION sensor and - later - the PROBA-V in the red, near-infrared, and shortwave infrared bands. These are used in a neural network approach which is trained with the best estimate of FCOVER from MODIS and CYCLOPES.

This is version 1 of this data set provided by COPERNICUS Global Land Service, downloaded from the data server at VITO in August/September 2015.
Data were downloaded in hdf5 file format with 1/112° grid cell resolution, organized in tiles of 10° latitude x 10° longitude. Data were block-averaged onto a 0.5° x 0.5° plate carree grid. Data are available for the latitude range 60°S to 80°N. Note, however, that limited solar illumination reduces the maximum northern latitude to smaller values during winter.
