The MOD13A1 V6 product provides a Vegetation Index (VI)
value at a per pixel basis. There are two primary vegetation layers.
The first is the Normalized Difference Vegetation Index (NDVI)
which is referred to as the continuity index to the existing National
Oceanic and Atmospheric Administration-Advanced Very High Resolution
Radiometer (NOAA-AVHRR) derived NDVI. The second vegetation layer
is the Enhanced Vegetation Index (EVI) that minimizes canopy background
variations and maintains sensitivity over dense vegetation conditions.
The EVI also uses the blue band to remove residual atmosphere contamination
caused by smoke and sub-pixel thin cloud clouds. The MODIS NDVI
and EVI products are computed from atmospherically corrected bi-directional
surface reflectances that have been masked for water, clouds, heavy
aerosols, and cloud shadows.
