*2.2. GLOBALBNU LAI*

GLOBALBNU LAI dataset was generated by the Land-atmosphere Interaction Research Group of Beijing Normal University (GLOBALBNU LAI) with 1 km spatial resolution and eight-day time step from 2000–2016, distributed by http://globalchange.bnu.edu.cn/. It is an improved LAI dataset on the basis of MODIS LAI dataset through a two-step integrated method. First, the modified Temporal-Spatial Filter (mTSF) developed by TSF [30] was used to process the lower quality data according to MODIS quality control (QC) and the data gaps and values were filled by making the best use of high-quality data. In the second step, the TIMESAT Savitzky–Golay (SG) filter was applied to post process the mTSF results to generate the final product [13]. The dataset is provided in NetCDF format with geographical coordinates.
