Green Vegetation Fraction (GVF)

Team Lead: Yunyue (Bob) Yu

Product Description

Green Vegetation Fraction (GVF) is the fractional green vegetation cover within a specific grid cell.

  • The VIIRS GVF algorithm is a modified version of the Gutman and Ignatov's (1998) GVF algorithm
  • The VIIRS GVF algorithm uses the VIIRS bands I1, I2 and M3 as input
  • The VIIRS GVF is derived form EVI

Product and Data Access

Products and data:

EDR Long Term-Monitoring

Documentation

The SNPP VIIRS GVF system generates two products:

  1. Weekly Global GVF at 4 km resolution
  2. Weekly Regional GVF at 1 km resolution (Lat 7.5°S to 90°N, Lon 130°E to 30°E)

Weekly (updated daily) GVF products are generated in Lat/Lon projection
