AI-generated Key Takeaways
-
MCD15A3H V6.1 provides a 4-day composite of global Leaf Area Index (LAI) and Fraction of Photosynthetically Active Radiation (FPAR) data at 500m resolution.
-
The dataset utilizes data from both MODIS sensors on NASA's Terra and Aqua satellites, selecting the best pixel within the 4-day period.
-
LAI represents the one-sided green leaf area per unit ground area, while FPAR quantifies the fraction of photosynthetically active radiation absorbed by vegetation.
-
Data quality information is provided through separate bands indicating cloud state, sensor, and retrieval algorithm details for both LAI and FPAR.
-
The dataset is freely available for use, redistribution, and sale through the NASA Land Processes Distributed Active Archive Center (LP DAAC).

Description
The MCD15A3H Version 6.1 Moderate Resolution Imaging Spectroradiometer (MODIS) Level 4, Combined Fraction of Photosynthetically Active Radiation (FPAR), and Leaf Area Index (LAI) product is a 4-day composite data set 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 4-day period.
