Global Data Sets of Vegetation Leaf Area Index (LAI)3g

A neural network algorithm was first developed between the new improved third generation Global Inventory Modeling and Mapping Studies (GIMMS) Normalized Difference Vegetation Index (NDVI3g) and best-quality Terra Moderate Resolution Imaging Spectroradiometer (MODIS) LAI products for the overlapping period 2000–2009. The trained neural network algorithm was then used to generate corresponding LAI3g and FPAR3g data sets with the following attributes: monthly temporal frequency, 0.5 degree spatial resolution and temporal span of July 1981 to December 2011.
