EROS MODIS Normalized Difference Vegetation Index: 2001-Present

eMODIS processes calibrated radiance data (level-1B) acquired by the MODIS sensors on the EOS Terra and Aqua satellites by combining MODIS Land Science Collection 5 Atmospherically Corrected Surface Reflectance production code and USGS EROS MODIS Direct Broadcast System (DBS) software to create surface reflectance and Normalized Difference Vegetation Index (NDVI) products.eMODIS通过结合MODIS陆地科学集合5大气校正地表反射率生产代码与美国地质调查局地球资源观测与科学中心（USGS EROS）的MODIS直接广播系统（DBS）软件，对EOS Terra与Aqua卫星上MODIS传感器获取的定标辐射数据（1B级数据）进行处理，以生成地表反射率与归一化植被指数（NDVI）产品。
