NOAA CDR AVHRR NDVI: Normalized Difference Vegetation Index, Version 4 (NOAA/CDR/AVHRR/NDVI/V4)
Version V4
The NOAA Climate Data Record (CDR) of AVHRR Normalized Difference Vegetation
Index (NDVI) contains gridded daily NDVI derived from the NOAA AVHRR Surface
Reflectance product. It provides a measurement of surface vegetation
coverage activity, gridded at a resolution of 0.05° and computed globally
over land surfaces.
