GVPS: Green Vegetation Fraction

The Green Vegetation Fraction (GVF) is the primary product of the Global Vegetation Process System (GVPS), which is important for land surface heat fluxes calculation in coupled land-atmospheric models. In this system, GVF is derived weekly using ACDF adjusted smoothed NDVI, which is based on the 6 selected year's smoothed NDVI.
