MUSES Leaf Area Index (LAI) 16-Day 30m Geographic Grid over Beijing Since 1984

The MUltiscale Satellite remotE Sensing (MUSES) product suite includes products with different spatial and temporal resolutions for parameters such as Normalized Difference Vegetation Index (NDVI), Near-Infrared Reflectance of Vegetation (NIRv), Leaf Area Index (LAI), Fraction of Absorbed Photosynthetically Active Radiation (FAPAR), Fractional Vegetation Coverage (FVC), Gross Primary Production (GPP), Net Primary Production (NPP). For more information about the MUSES products, please refer to this website (https://muses.bnu.edu.cn/).

This dataset is the MUSES LAI product at 30 m spatial resolution and 16-day temporal resolution over Beijing. The MUSES LAI product is provided on Geographic grid and spans from 1984 to 2021 (continuously updated). It was generated from time-series Landsat surface reflectance data using general regression neural networks (GRNNs)  (Xiao et al., 2014; Xiao et al., 2016). The MUSES LAI product is spatially complete and temporally continuous.
