The Enhanced Vegetation Index (EVI) is generated from the Near-IR, Red and Blue bands of each scene, and ranges in value from -1.0 to 1.0. See Huete et al. (2002) for details. This product is generated from the MODIS/MOD09GA surface reflectance composites.
增强植被指数(EVI)由每个场景的近红外、红色和蓝色波段生成,数值范围为-1.0到1.0。详见Huete等人(2002)。这个产品是由MODIS/MOD09GA表面反射率合成的。
