MODIS/Aqua Vegetation Indices 16-Day L3 Global 500m SIN Grid V006

Version 006
  • Abstract
    The MYD13A1 Version 6 product provides a Vegetation Index (VI) value at a per pixel basis. There are 2 primary vegetation layers. The algorithm for this product chooses the best available pixel value from all the acquisitions from the 16 day period. The criteria used is low clouds, low view angle and the highest NDVI/EVI value. 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), which has improved sensitivity over high biomass regions. Provided along with the Vegetation layers and the two Quality Assurance (QA) layers and Reflectance bands 1 (Red), 2 (Near-Infrared), 3 (Blue), and 7 (Mid-Infrared), as well as four observation layers. Validation at stage 3 has been achieved for all MODIS MOD/MYD13 vegetation products.
