MUSES Leaf Area Index (LAI) Derived from AVHRR Data 8-Day Global 0.05º Geographic Grid Since 1981

<p>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).&nbsp;For more information about the MUSES products, please refer to this website (<a href="https://muses.bnu.edu.cn/">https://muses.bnu.edu.cn/</a>).</p> <p>This dataset is the MUSES global&nbsp;LAI product at 0.05&ordm; spatial&nbsp;resolution&nbsp;and 8-day temporal resolution.&nbsp;The MUSES LAI product is&nbsp;provided&nbsp;on Geographic grid and spans from 1981&nbsp;to 2019 (continuously updated).&nbsp;It was generated from time-series&nbsp;Land Long-Term Data Record (LTDR)&nbsp;Advanced very high resolution radiometer (AVHRR)&nbsp;daily surface&nbsp;reflectance product&nbsp;(Version 4) using general regression neural networks (GRNNs) &nbsp;(Xiao&nbsp;<em>et al</em>., 2014; Xiao&nbsp;<em>et al.</em>, 2016). The MUSES LAI product is spatially complete and temporally continuous.</p> <p><strong>Dataset Characteristics:</strong></p> <ul> <li>Spatial Coverage: 180&ordm; W&nbsp;&ndash; 180&ordm; E, 90&ordm; S&nbsp;&ndash; 90&ordm; N</li> <li>Temporal Coverage: 1981&nbsp;&ndash; 2019</li> <li>Spatial Resolution: 0.05&ordm; (approximately 5 km)</li> <li>Temporal Resolution: 8 days</li> <li>Projection: Geographic</li> <li>Data Format: HDF</li> <li>Scale: 0.01</li> <li>Valid Range: 0 &ndash; 1000</li> </ul> <p><strong>Citation&nbsp;</strong>(Please cite this paper whenever these data are used)<strong>:</strong></p> <ol> <li>Xiao Zhiqiang, Jinling Song, Hua Yang, Rui Sun and Juan Li.
