MYD13A1.006 Aqua Vegetation Indices 16-Day Global 500m [deprecated]

  • This MODIS/MYD13A1 V6 dataset provides Vegetation Index (VI) values, including NDVI and EVI, at a 500m resolution.

  • The dataset covers the period from July 4, 2002, to February 10, 2023, and has been superseded by a newer version.

  • NDVI and EVI data are derived from atmospherically corrected surface reflectances and masked for various factors like clouds and water.

  • This dataset is provided by NASA LP DAAC at the USGS EROS Center and has no restrictions on use, sale, or redistribution.

  • Users should consider transitioning to the updated MODIS/061/MYD13A1 dataset for continued analysis.

Description

The MYD13A1 V6 product provides a Vegetation Index (VI) value at a per pixel basis. There are two primary vegetation layers. 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) that minimizes canopy background variations and maintains sensitivity over dense vegetation conditions. The EVI also uses the blue band to remove residual atmosphere contamination caused by smoke and sub-pixel thin cloud clouds. The MODIS NDVI and EVI products are computed from atmospherically corrected bi-directional surface reflectances that have been masked for water, clouds, heavy aerosols, and cloud shadows.
