Global Experimental Bi-Weekly Normalized Difference (GLEND) Vegetation Index
Entry ID: GLEND_NC00260

[ Update this Record ]

Summary
Abstract: The vigor and density of green vegetation can be monitored through
examination of the spectral reflectance of the vegetation in the visible
and near infrared areas of the electromagnetic spectrum.

The NOAA Global Vegetation Index (GVI) uses sampled visible and near IR AVHRR
GAC data to produce a vegetative index called the Normalized Difference
