Abstract：

Based on the MODIS leaf area index (LAI) products, the authors designed an algorithm with maximum fraction of absorbed photosynthetically active radiation in a day to recompile a new reprocessing dataset, in which the vegetation types were input to the model for the LAI analysis. The resolution of the dataset were changed from 500 m to 0.05°. By validation with 280 public measured LAI test sites, the square of the linear fitting correlation coefficient of the reprocessing dataset reaches 0.748. The dataset includes 8-day, monthly, and yearly global LAI with resolution of 0.05°. The scale factor is 0.1. The dataset is archived in .tif format, and consists of 1239 data files with data size of 29.9 GB (Compressed into three files with 2.48 GB).
