AI-generated Key Takeaways
-
This dataset provides 8-day composite Leaf Area Index (LAI) and Fraction of Photosynthetically Active Radiation (FPAR) data globally at 500m resolution from the Aqua sensor.
-
The data is available from July 4, 2002, to February 18, 2023, and is provided by NASA LP DAAC at the USGS EROS Center.
-
Key bands include
Fpar_500mandLai_500m, along with associated quality and standard deviation information. -
The dataset has no restrictions on use, sale, or redistribution, but it has been superseded by MODIS/061/MYD15A2H.

Description
The MYD15A2H V6 MODIS combined Leaf Area Index (LAI) and Fraction of Photosynthetically Active Radiation (FPAR) product is an 8-day composite dataset at 500m resolution. The algorithm chooses the "best" pixel available from all the acquisitions of the Aqua sensor from within the 8-day period.
