The MCD15A3H version 6.1 medium resolution imaging spectrometer (MODIS) level 4, combined fraction of photosynthetically active radiation (FPAR) and leaf area index (LAI) products are a 4-day composite dataset with a pixel size of 500 meters. The algorithm selects the best pixel available from all the acquisition of MODIS sensors on NASA's Terra and Aqua satellites within 4 days. LAI is defined as one-sided green leaf area per unit area in broad-leaved tree crown and one-half of total coniferous surface area per unit area in coniferous tree crown.
MCD15A3H LAI data is stored in tif format. The file name is "MCD15A3H_yyyy_mm_dd. tif", where yyyy represents the year, mm represents the month, and dd represents the date. E.g. MCD15A3H_ 2006_ 01_ 01.tif represents the tif document describing the leaf area index from January 1, 2006 to January 4, 2006.
Data reading method: All tif files in the dataset can be opened directly with Arcgis.
