We are in the process of migrating all NASA Earth science data sites into Earthdata from now until end of 2026. Not all NASA Earth science data and resources will appear here until then. Thank you for your patience as we make this transition.Read about the Web Unification Project
Description
The MOD15A2H Version 6 data product was decommissioned on July 31, 2023. Users are encouraged to use the MOD15A2H Version 6.1 data product.
The MOD15A2H Version 6 Moderate Resolution Imaging Spectroradiometer (MODIS) combined Leaf Area Index (LAI) and Fraction of Photosynthetically Active Radiation (FPAR) product is an 8-day composite dataset with 500 meter (m) pixel size. The algorithm chooses the “best” pixel available from all the acquisitions of the Terra sensor 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 nanometers (nm), absorbed by the green elements of a vegetation canopy.
Science Datasets (SDSs) in the Level 4 (L4) MOD15A2H product include LAI, FPAR, two quality layers, and standard deviation for LAI and FPAR. Two low resolution browse images, LAI and FPAR, are also available for each MOD15A2H granule.
The following changes and improvements were implemented for inputs to MODIS Version 6 LAI and FPAR data products: (1) The Version 6 product uses the daily L2G-lite surface reflectance as input as opposed to MODAGAGG used in Version 5, (2) Products are generated at native resolution of 500 m rather than the 1000 m of the Version 5, and (3) Version 6 uses an improved multi-year land cover product.
