MOD13A2.006 Terra Vegetation Indices 16-Day Global 1km [deprecated]

  • This MOD13A2 V6 dataset provides 16-day global vegetation indices (NDVI and EVI) at 1km resolution, derived from MODIS Terra satellite imagery.

  • The dataset has been deprecated and superseded by a newer version (MODIS/061/MOD13A2), which users should consider instead.

  • NDVI serves as a continuity index to existing NOAA-AVHRR derived NDVI, while EVI offers enhanced sensitivity in high biomass regions.

  • The algorithm selects the best pixel value from a 16-day period based on low clouds, low view angle, and highest NDVI/EVI value.

  • Data is freely available for use, sale, or redistribution, covering the period from 2000-02-18 to 2023-02-02.

Description

The MOD13A2 V6 product provides two Vegetation Indices (VI): the Normalized Difference Vegetation Index (NDVI) and the Enhanced Vegetation Index (EVI). The NDVI 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 EVI has improved sensitivity over high biomass regions.

The algorithm for this product chooses the best available pixel value from all the acquisitions from the 16-day period. The criteria used are low clouds, low view angle, and the highest NDVI/EVI value.
