The dataset includes five global LAI remote sensing products (MODIS, GEOV1, GLASS, GLOBMAP, JRC-TIP) and Land-SAFLAI products in Africa. The multi-year data is downloaded and and the monthly and annual averages based on pixels are carried out to obtain the global multi-year (2003-2010) LAI distribution, and the African multi-year (2007-2010) LAI distribution. The uncertainty and relative uncertainty information of each product are also extracted to generate global and regional distribution maps. The data set has a spatial resolution of 0.05 ° and a temporal resolution of months. It is stored in binary format. Each pixel is divided into 12 layers, representing 12 months. Its purpose is to compare the magnitude, distribution and uncertainty information of existing global LAI remote sensing products, and to provide data analysis basis for researchers engaged in quantitative remote sensing research of vegetation and application of LAI remote sensing products.
