Leaf Area Index - LAI

This global database of Leaf Area Indices (LAIs) is derived using input from the Moderate Resolution Imaging Spectroradiometer (MODIS) operational reflectance product (MOD09). The LAI datasets were created by reprocessing the MODIS LAI products using a two-step integrated method. First, a modified temporal spatial filter (mTSF) was used based on the TSF method developed by Fang et al. (2007; 2008). This to fill the gaps of the MODIS LAI data and process the lower quality data according to the quality control (QC) value information by making the best use of the high quality data. Then the TIMESAT Savitzky-Golay (SG) filter (Jonsson and Eklundh, 2004) was applied to generate the improved MODIS LAI products.
