description: The MODIS Terra MOD13A2 Version 6.1 product provides Vegetation Index (VI) values at 1 km spatial resolution on a per-pixel basis. The dataset includes two primary vegetation indices: the Normalized Difference Vegetation Index (NDVI), which maintains continuity with NDVI derived from NOAA-AVHRR observations, and the Enhanced Vegetation Index (EVI), which improves sensitivity in regions with high vegetation biomass. The product is generated as a 16-day composite, where the algorithm selects the best available pixel from all acquisitions within the compositing period based on criteria such as low cloud contamination, low view angle, and the highest NDVI/EVI value. In addition to the vegetation index layers and two quality assurance layers, the product includes reflectance bands 1 (red), 2 (near-infrared), 3 (blue), and 7 (mid-infrared), as well as four observation layers.
