Description

The MCD15A2H Version 6 data product was decommissioned on July 31, 2023. Users are encouraged to use the MCD15A2H Version 6.1 data product.

The MCD15A2H Version 6 Moderate Resolution Imaging Spectroradiometer (MODIS) Level 4, Combined Fraction of Photosynthetically Active Radiation (FPAR), and Leaf Area Index (LAI) product is an 8-day composite dataset with 500 meter pixel size. The algorithm chooses the best pixel available from all the acquisitions of both MODIS sensors located on NASA's Terra and Aqua satellites from within the 8-day period.

LAI is defined as the one-sided green leaf area per unit ground area in broadleaf canopies and as one-half the total needle surface area per unit ground area in coniferous canopies. FPAR is defined as the fraction of incident photosynthetically active radiation (400-700 nm) absorbed by the green elements of a vegetation canopy.

Known Issues

Improvements/Changes from Previous Version

  • The Version 6 product uses the daily Level 2 Gridded (L2G)-lite surface reflectance as input as opposed to MODAGAGG, a MODIS daily aggregated surface reflectance product, used in Version 5
  • Products are generated at native resolution of 500 meters rather than the 1,000 meters of the Version 5.
  • Version 6 uses an improved multi-year land cover product.
