Vegetation Health

Team Lead: Felix Kogan

Product Description

  • Vegetation health (VH) is a method derivation of global vegetation condition from VIS and IR channels of afternoon operational polar-orbiting satellites
  • The method is based on three bio-physical and ecosystem laws
  • The global VH (GVH) output is produced every week
  • Briefly, algorithm includes retrieval of orbital VIS and IR, calculation of NDVI and BT, their daily and weekly mapping & development of time series, comprehensive NDVI & BT massaging and calculation of three VH indices
  • The developed products include 16 & 4 km AVHRR/GVH and 4 km VIIRS/GVH
  • High resolution (1 km) Vegetation Health Products from VIIRS for recent years(since 2015) are avalible online
