GOES-13 Sounder IR data is not available. All products from GOES-13 (GOES-East) Sounder IR data have been halted and distribution has been stopped except the Sounder ASOS SCP products for CONUS, which are replaced with GOES-East Imager ASOS SCP products for CONUS. Engineers are investigating the problem.

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.
