The Normalized Difference Vegetation Index is generated from the Near-IR and Red bands of each scene as (NIR - Red) / (NIR + Red), and ranges in value from -1.0 to 1.0. This product is generated from the MODIS/MOD09GA surface reflectance composites.

归一化植被指数由每个场景的近红外和红色波段生成,为(近红外-红色)/(近红外+红色),数值范围为-1.0至1.0。这个产品是由MODIS/MOD09GA表面反射率合成物生成的。
