Vegetation: eMODIS NDVI percent of average
FEWS NET uses satellite-derived vegetation products generated from the Moderate Resolution Imaging Spectroradiometer (MODIS). Known as "eMODIS," these images compare the real-time Normalized Difference Vegetation Index (NDVI) data against historical records. These images capture NDVI as a percentage of normal and NDVI anomalies. Read more about NDVI.
