Abstract
A global multi-decade long-term Leaf area index (LAI) record from remote sensing measurements is required for global change modeling and analysis. The dataset is generated through the fusion of MODIS and historical AVHRR data based on global pixel-based AVHRR SRMODIS LAI relationship which is established with AVHRR data and LAI derived form high quality MODIS observations in the overlapping years from 2000 to 2006. Based on this relationship, historical AVHRR retrieval from 1981 to 2006 is constrained with high quality MODIS observations. The comparisons of the results from 2000 to 2006 show high consistency between the derived AVHRR and MODIS LAI dataset. The derived AVHRR and MODIS LAI were directly validated with 120 field measurements in global 36 sites with various vegetation types, with RMSE of 0.91 and 1.01, respectively.
